Mason Bottle DIY Kit

Purchased as part of gift for my neice’s baby shower. It was on her registry.

I love everything about this system except for the nipple flow. Which I stated in more depth in my nipple review.

By far the best bottle ever! This is my fourth kiddo and the bottles we used before filled my sink with pieces and always smelled funny and had a haze on them. The Mason bottle is easy to use and grows with your growing child. Definitely by far the best bottle ever!

nice product. will purchase more.

I love how easy it is to use mason jars as bottles now! And the slow flow nipples have reduced my little ones split ups, which has been amazing! Easy to clean and store :)

We mason jars as cups in our house so we already had tons when I found the DIY kits and was so excited to order some for my little one. They’re great as far as fitting on the jars, look, and quality. My little one hasn’t arrived yet so I can’t review how well the actually work yet but I’m so excited to use them and will definitely be ordering more if all goes well

I think it’s a great idea. Yes the bottles are very hardy and don’t break easily. However my son has dropped it on his toe, twice, and that is going to be a problem. He is 16 months old and very busy. So we might have to wait till he’s older and more self aware before he can use these regularly.

I ordered this as a baby shower gift and the mom-to-be was thrilled! Her exact words were, "I am so excited about this- I can wait to use it." Ordering was easy and shipping was fast- faster than I expected. I will keep these in mind for fun baby gifts.

Loveee the jar set! It’s perfect and the best part is no plastic!

Love my mason bottles!! So glad that i found them. Easy to clean, store, and i love how "clean" it is compared to using plastic bottles. My baby loves them and I cant wait to use the other products in the future!

I love how versatile these mason bottles are! Since my LO is on to the 8-ounce bottles, I use my 4-ounce jars for baby food. And we can use the 8-ounce jars for sippy cups now... perfect setup for minimalistic mamas! I also try to limit our plastic exposure, so that’s another win.

We are loving this. My EBF baby latches to this bottle better than any. I am so thankful.

So easy to clean, great for EBF babies, and I don't have to worry about the toxins in plastic pieces!

Great idea; love using my own jars. We are getting used to the nipple as it isn't my baby's favorite yet.

I am so excited to be able to use the mason jars we have collected over the years as bottles. Mason jars are super easy to clean in the dishwasher and are very durable so I have high expectations!

Bought as a gift and the soon to be mom loves it!

Love love love these! So much easier to clean glass than plastic, and the silicone cover fits my jars I already had at home perfectly, our sweet baby boy loves the nipple and hasn’t had any issues. I finally have a use for all these jars I have laying around that were too small for most canning projects.

Perfect for my baby! I'm advertising to all my friends how versatile they are.wamt more!

Love that the hole is small, makes baby work!

Great fit to jar, no leaking, easy to assemble

I love this idea and have loved the product so far! I love that’s it’s not a bottle of plastic, it’s durable and versatile. I actually purchased some sippy cup tops as well that fit the glasses so I am using the set up for both my infant and my toddler, cuts down on the amount of “bottles”/ cups I have to keep in my limited storage cabinet!

This was a gift. The couple was very excited to get it and believe it will be great for their baby. I thought it was a great idea, but for the price the kit should have included the screw bands and the mason jars themselves.

Love the concept and simplicity! We haven't yet been able to use them yet. Maybe is due soon!

I love using these bottles! They’re so versatile; I can pair them with any mason jar in the house. I wish I had known about them with my older kids. They fit great in my diaper bag and my baby has not had any issues transitioning to them.

Love this idea I was worried glass would be too heavy but it's definitely not.. its also much easier to clean using the glass bottles and gives me better piece of mind over the plastic I was using before. The kit is a nice starter set I did end up purchasing the plastic rings because they work much better than the metal ones. I had some difficulty with the metal ones at first but I eventually got the hang of it. Storing the milk in the glass bottles also greatly reduced the amount of bottles I was washing. Great idea overall and im glad I came across this site!

I highly recommend everything from Mason! If you want what is best for your baby. Please take my advice- go with Mason. Plastic bottles are the absolute worse and Mason has dotted their i’s and crosses all of their t’s when they came up with these kits. Well worth the price! I can’t say enough about these products!

We absolutely love all our mason bottle products! It’s been a great transition for breastfed babies! I recommend to anyone. Also customer service is top notch!

This has been a game changer for us!! No more smelly plastic bottles for us! I would recommend to anyone.

This was a baby shower gift so I am not the one using it.

My son is a breastfeed baby, he didn’t want anything to do with a bottle. I needed him to take a bottle before returning to work. I saw an ad on Instagram for mason bottle, I decided to give it a try, and my son loved it! Mason bottle is the only one he takes now.

Just what I wanted When I was assembling my baby registry I thought about what bottles I wanted to use for expressed breast milk. I've used mason jars for drinking nearly everything for myself for a few years now and I said to my husband "You know what I wish they had: mason jar baby bottles." I love jars because they are so easy to clean and sterilize. Lo and behold, I found they exist and the DIY kit was so affordable. The product of my dreams and my infant loves them. Thank you Mason Bottle for empowering a working, breastfeeding mother who loves her baby and the planet.

A million times worth it! I originally wanted glass bottles, but the pricing of them was insane for multiples! We already use mason jars for our kitchen storage and just about everything else, so it just made sense to us! These DIY kits were so helpful for us! My son is almost 8 months and we still religiously use these every day. People comment on them all the time and I share with as many people I can about how wonderful they are! Super easy to clean, hand wash or throw in the dishwasher. I like to wash the nipples by hand, and just rinse the metal rings and put on my boob grass drying rack. They are easy for my son to hold, and he’s dropped them with the silicone sleeve on multiple times and no cracks or breaks! Mason jars are super durable. I’m going to get the silicone straws in the coming months to start transitioning him into a sippy cup. I love that I can use his jars for bottles, sippy cups, open ended cups, and then storage later on! They always have a purpose! That’s saves a lot of money.

Worth it It’s worth every penny to get this bundle pack. I love that I can use a mason jar instead of a plastic bottle. The only negative is that the nipple needs to be longer. My daughter is nursing but takes a bottle well. Unfortunately she can’t drink from this nipple because it doesn’t fit properly in her mouth. I really hope they make a longer nipple soon so I can buy some for my next baby!

LOVE Seriously, where were these when I became a mom over 4 years ago? We’ve always preferred glass bottles but never found a reasonably priced set. This is perfect!! Just buy the DIY set and boom, you have everything you need if you already have jars. They’re super cute too! Bonus!

Never Turning Back I get so many compliments on these bottles. I love that nothing is really wasted after the bottle stage. So many uses. I’m thankful for mason bottles. Never going back!! They are a family favorite!

versatile Very nice to be able to use this easily as busy moms. Also the rubber makes it a wonderful chew toy for the children

Convenience I really like that it's a simple Mason bottle and a Mason jar I often him a tired mom that leave bottles everywhere so it's nice to just grab another jar in be ready to go

amazing products! absolutely love the products! Amazing quality and easy to clean.

Will never go back! I love these bottles! The fact they are dishwasher safe, not plastic, convenient, safe for baby, durable....I will never go back to the other brands. Even handwashing the metal rings isn't a big deal because everything else goes in the dishwasher. I used these with baby #2 and am currently pregnant with #3 and can't wait to use these again! I got so many compliments on them and had so many conversations with strangers even- these are a great, affordable option and most importantly, a safe option. Highly recommend to every new parent.

Best One Out There Best bottle on the market for moms (or dads!) who want something healthy, safe, and without chemicals. It even looks cute!

Awesome Bottles for Conscious Families We finally tried the Mason Bottle for our 4th baby and we love the convenience of simply using it with the Mason jars in our home. No bundles of plastic bottles to tumble out of the cabinet, like they would did with the stuff we tried for our other babies. They're easy to transport, fit in every bottle slot or cup holder we use and super easy to heat - no worrying about even the "safe" plastics leaching into our baby's milk. Now that we're expecting Baby #5, we will definitely be choosing Mason Bottle again!

Easy to use system! The system is straight forward and very easy to use. I have the 4 oz system as I pump milk and put directly into a 4 ounce jar. The sleeve secures over even on the textured jars which we have. Nipples fit secure in metal rings, but I have, also, used Mason Bottle's plastic rings. I love the convenience of their products being dishwasher safe.

Love! We just got ours in today! Zayne is 11 days old and took right to it, we love the breast-like nipple (our baby gets breast & bottle)! Definitely recommending to our friends & family!

Sanity Saver Mason bottles have saved my sanity! My family uses Mason jars for various purposes in our daily life. Having bottles and toddler cups that utilize something I already have saved space in my kitchen. Eliminating clutter and having something that is easy to clean has saved my sanity!

Happy Baby & Momma! Baby and I love these products. My baby likes the nipple, unlike some other bottles. I love that I can use my own Mason bottles! And the silicone sleeve has measurements on it. Highly recommend to everybody!

Mason Bottle DIY kit I LOVE this concept!!! Made in U.S.A. is my #1 priority...#2 no BPA or phylates leaching into the bottle...#3 reusable for storage...I love this brilliant concept.

No issues-Really liking! We are using the mason bottle slow flow nipples for our new born foster son. He had feeding issues when he was first born. When we brought him home at 1 week, we tried the mason bottle and the one the hospital gave him and he seemed to do better with the mason bottle since it has the wide base. We're loving it!

Great for baby minimalism I had my doubts because I had heard there were problems with leaking, but we haven’t had any problems at all! We use a 4oz mason jar with a metal sealing ring, and it works just great. The silicone sleeve is nice as a temperature buffer, and I love that there is no plastic. My father in law warned me that my hippie millennial ways would land me cleaning up a bunch of broken glass, but my daughter has definitely thrown it out of her crib and it has survived. We go back and forth between mason bottles and como tomo, and they both work equally well. What’s even better about the mason bottle is that I can store my breast milk in the same glass jars that I warm up and put the nipple on, and when we’re done with our baby days we don’t have a ton of bottle parts to store until the next one. Minimalist win!

Minimal and simple is good I am loving this product because it is not only better for my baby to drink out of an easy clean glass jar that I can sanitize. But it is a good product for me in achieving the minimalist lifestyle that I aspire to have. Mason jars were already something that I used at home and adding the bottle top and sleeve were easy additions to my kitchen. I love this product and would recommend it for everyone it’s very easy and safe for your baby.

LOVE LOVE LOVE My husband and I were so ecstatic to get our mason bottle kits in the mail! Our little girl has taken to them immediately and even seems to have less gas than the anti colic bottles we were previously using. A cinch to clean and I now store all of my expressed breastmilk in the mason jars and just pop the nipple on top! Such a breeze.

Love the concept! The 4 ounce set up is perfect for bottles under 4 ounces. The jar itself Actually holds less that 4 ounces perfectly (so good for bottle feeding 0-3months). I like the flow of the bottle but it is slightly faster than an Avent Natural size 1. It took my baby a bit to get use to the flow, and there was a lot of spillage around the mouth (not coming out of the vent holes which is great). Overall I love this bottle!! Love the system and the simplicity. I have already recommended the mason bottle to my friends!

Simply the best! I am "the Grandma" with grand baby #1. Mom and dad use Dr. Brown's plastic bottles; besides being plastic, they are a pain in the neck to clean. I searched the internet for glass bottles and seemed most had fragile glass or leaky lids, so I passed. Somehow I stumbled on these mason jar bottles and they are simply the best! Baby did not blink an eye when fed with the mason jar bottle. She is 8 months old and I recently added the sleeve, which, go figure, she likes to scratch with her nails and poke at the holes.... all about the hands! I did have trouble getting the nipple in, but finally figured that patience helps, and to just push the edge up over the lip and then push slowly around the circle with a finger from the underside. Mason jar bottles are now at the top of my list when giving baby presents !

Great For Our Family I am a first time mom just trying to make life a little bit easier on my husband an I, and these were a huge help. I absolutely love the fact that you don’t have to use a bottle brush and there are not a million tiny pieces to disassemble and reassemble every time you wash your bottles. The other main seller for me was, you can freeze your breastmilk in the same container that you feed your baby with. There aren’t many other reasonably priced bottles out there that’s can boast the same.

Love love love I absolutely love these bottle were the only bottles my son would take I bought them again for my sister who is pregnant. Now that my son has out grown the bottle nipples I have their sippy nipples and again it's the only sippy he will use. So glad I found this product love that it grows with my baby. Has absolutely no plastic. And that it's just a Mason jar I already have. My only issue is the silicone sleave is super thin once baby starts throwing it's not ideal. I did find a silicone cover that works perfect my son drops and throws these and the don't break. Thank you for making an amazing product for moms who don't want to use plastic

Such a great idea I always pumped and stored my milk in 4oz mason jars, so when I saw the Kickstarter for these I was so excited! Unfortunately at that time my first son was already past the bottle stage, when I found out I was expecting our second I knew I was going to try these! They fit perfect on my 4oz mason jars I use for pumping and they are so cute. I can’t wait to use them ❤️

Like a treat Would you describe buying baby bottles as giving yourself a treat? Well, believe it or not, Mason Bottle's products made me feel like having a treat. The chic, minimalist packaging and products, and the attractive yet gender-neutral color of the silicone sleeve made the un-boxing of my delivery a delightful experience, especially for this first-time mom. Thank you for this memory, Mason Bottle!

Only bottles used at home I purchased both kit sizes in preparation for my first baby and haven’t looked back. She loves them and so do I. Easy to use, clean, store, and repurpose once the bottle phase is complete. I was bummed when my daycare refused to take glass (even with the silicone sleeve) but we still use mason bottle at home without issue. Would definitely recommend to others.

Great product... just not right for my baby I just wanted to provide an update on the bottles, now that my little one has actually arrived and used them. The bottles themselves are great -- no problems there! Sturdy, great idea and concept, environmental friendly. Unfortunately (and I am very bummed by this...) they just aren't the right fit for my baby. It turns out she has reflux and just gets too much air when she uses these bottles. I am hoping once she gets bigger and her reflux goes away, we can try them again. I have also noticed that because of the wide-mouth/base, it is sometimes hard to keep milk in the nipples... which may lead to the baby taking in more air. I so wanted these bottles to work out for our family, but they as of right now they don't :( Keeping my fingers crossed that they will in the future!!!

Glass bottles and can use them later! I spent time researching which glass bottles were best and was about to buy several different types when I discovered the Mason bottles. I'm so excited to have discovered an item that can mostly be reused later for other things! I plan on eventually using the mason jars for baby food storage and drinking cups so really the only part I won't use for years to come are the nipples. I also love that the wide nipples are more similar to the breast than many other glass bottles I found.

Great baby shower gift Will be giving these at every baby shower I go to. Love that I can boil my bottles to sanitize! Then when I'm done make jelly! Ha! Can't wait for the sippy nipple! Hurry up my little man's growing Fast!

Great Quality I haven't had a chance to use these yet (baby is still cookin' for one more month!). However, I have put my bottles together and they seem very sturdy and high quality. I am not concerned about the glass breaking, since Mason jars are thick and I rarely have them break on me. These bottles will be so much easier to clean than plastic bottles -- not to mention will last much longer and help the environment! I am so excited to see how my baby takes to them and will update after she's born.

So neat! We drink out of mason jars at home so our cupboard is full of them. Such a great way for our babe to be able to use them as well!

Perfect! I got this DIY Kit and is perfect! Love the fact that is so versatile. I already have few mason jars (who doesn't?) And can easily use this DIY on all of them. I use them for breast milk and also to keep some soft food there when I'm on the go. Love it!

Excellent value Best bang for your buck! Easy to use, and so versatile!

AMAZING!!! These bottles are amazing!! So easy to clean!! Love them so much I am going to buy more

Great Product! While we are still awaiting our little bundle, I already have the cupboard stocked with Mason Bottles! I can't say enough about the quality and functionality of this product! All the pieces came perfectly packaged in eco-friendly boxes. The materials are durable, interchangeable, and as a bonus ADORABLE! I love that pieces can be easily washed and used with jars that I already have on hand. Thank you!

Only bottle needed Once we got these we switched over to only mason bottles I have so many mason jars and love that I can freeze my milk in them and have them ready to go by just popping the nipple and cover on I've bought three of these kits one for a friend and one in each size for myself they are the best!

the only bottle I wish I'd ever owned This is a dream come true. I wish I hadn't invested in so many other types of bottles before these were dreamed into existence. The cleaning is wonderful - no special brushes needed - so versatile. This kit is now my favorite new mama gift!

Great starter set This was the first item I bought from Mason Bottles for my breastfed daughter and she took to this bottle with no issues. This set is great as it comes with everything you need, except the jar, to try out the bottle and see if it works for you. The jars can be easily purchased at Walmart or Target and if it doesn't work out you have extra jars for drinking or storage.

Great gift idea I received these shortly after my son was born as a gift from a friend also with a baby. I loved not having to use plastic and also how easy all the pieces of this product were to clean. My son took to these bottles right away. Nowadays we still use the mason jars for snack containers.

Love these!! I've bought four of these kits! I bought one four oz and realized I'd rather have the silicone sleeve for the eight ounce. It gets more use out of my toddler than when used as a bottle for my two month old. Kit is great. Baby latched. Makes a great gift!

Great idea Love these! My mom has always used mason jars for glasses so these worked great to leave for bottles at Grandma’s. The nipples are great quality too.

Best ever! I purchased this set just so I could have all the components to try. While the cap doesn't fit my rings if it did I'd love that. But the sleeve is super nice because it makes it so much easier for kiddo to get a grip on the bottle when trying to learn to hold himself.

Best Baby Bottle Ever! We have LOVED the convenience and design of the Mason Bottle! My little one easily switches between nursing and the Mason Bottle. The nipple design mimics the breast more than any other nipple we have found! I also love the peace of mind that comes with using a safe and eco friendly product. I knew I wanted to use glass jars with my baby but many on the market are pricey! Using my existing mason jars at home has been a money saver and convenience for my family! Thank you for creating a ingenious, well-made, safe and timeless product!

Prefect kit The mason bottle is the prefect no waste bottle. Mason jars are so cheap and this kit is everything you need. The sleeves aren't the greatest but everything else in the kit is wonderful. The mason bottle is the best bottle you will ever use! And then after you are done with bottles store baby food in them or snacks.

Perfect! I have extra Mason jars so this kit is perfect! This kit comes with everything except the jar. It's a little more cost effective as well. I love all of the options!

Downright PERFECT This is what we started with. We were able to repurpose jars we had at home already. The sleeves we didn’t really use, only when going outside with the cups since they didn’t stay on the best. The lids and nipples are an excellent match to any mason jar you already have!

Love this! So glad we found this system to use. As a new mom, I was worried about which bottle would be right for us. This answered so many needs for our family. My son has no issue going back to breast feeding. The nipple goes right on the mason jar so there’s no reason to store my breast milk in plastic. I couldn’t have asked for a more simple way to feed my child when I have to be away from him. I have already recommended this product to others!

Wish I had this 7 kids ago I'm so glad I found these. I have used about every bottle under the sun, having 8 kids. I really like not having to buy the bottle because I already had the Mason jars.Also no nasty plastic to store the milk in. I pump and then store them right in the freezer. Looking forward to getting the 8 oz ones soon. My son took them and had no problem going back and forth between nursing and this bottle.

Gift Giving I love to give gift that can be used on a daily basis, that are environmentally sound, and easy to use. This is it, wonderful gift to the new family!

Clean, simple, and practically wasteless. My family tries to be really conscious of our environmental footprint, and that's is what initially drew me to this product. I use Mason jars already in my home to buy in bulk and store food, and so I already had plenty on hand. When I became pregnant with my first... I became absolutely terrified of all the hundreds of different bottle options and all the various plastic (unrecyleable) parts. The photos of "organized bottle storage" systems just looked like a poorly contained mess. So when I first purchased my mason bottle diy kits I had desperately high hopes, which thankfully were more than exceeded. Everyone who sees me use these asks about them. They never get the dingy haze of plastic bottles, and I store them in the same space as my drinking glasses. So no wasted space on my countertops. No bottle brushes, no plastic bottle drying area, no wasted parts. When we're done with them I'm going to donate them to my local animal shelter for feeding baby animals. These are the best bottle on the market. I give them a hundred stars, 10/10 for sure.

Love this bottle system! When searching for a bottle system for my mostly breastfed son, I stumbled across Mason Bottle on Instagram and immediately wanted to try it out! We've been using these bottles for 4 months and have never had a problem. My son took right to them with no fuss, and storing my breastmilk is never a hassle in the freezer or the refrigerator. Would absolutely recommend to any new parents who want to cut down on plastic use as well. Overall 5 stars!

LOVE THESE!! Thankfully, my baby girl loved these nipples because I love the idea of her drinking out of non-toxic glass. These work very well without any leaking issues! Not to mention they are super cute!! She is breastfed so we've continued with the slow-flow nipples and she doesn't seem to have any problems. Oh and the customer service is FANTASTIC! We had an issue with one of the nipples and they went above and beyond to resolve the problem. I just ordered another set! Can't wait for the sippy lids to come out!! :)

So simple! I love how this DIY kit fits to your own 4oz and 8oz mason jars. The silicone sleeve helps your baby get a good grip while providing a little cushion for falls. The nipple has two vents that do a great job of keeping the pressure regulated. One thing I noticed upon inspection with milk inside is when you tip it and push on the nipple where the mouth of your baby would go, the nipple react in a way that mimics actual breast in the way it releases the fluid. It's also not to heavy like other, longer 8oz glass bottles, giving your infant the ability to hold it up on his/her own easily. My one issue is that the metal ring on the jar can get rusty. The nature of bottle use for infants is one that is rarely away from the sink. It would be nice if Mason Bottle came up with an alternative screw cap that would not rust so easily as the standard screw on caps. Really a fabulous product! I wish I had more. I wish I knew about these before I had my shower, and avoiding all the plastic bottles I ended up with. They will also make great glasses after bottle use is over. Also happy to see the Made in the USA mark on the product as well.

Simply Genius! The next best thing to breastfeeding and the world's best shower gift! I love that I will never again have to buy a baby bottle because I already have tons of mason jars and they are so easy to clean. Our little guy loves his bottle!

Multi-use Perfect! Bought one for me to use in the future, and another for a friend that's pregnant. Love that it'll work with jars I already own! Everything is great quality! The silicone sleeve works great for my own use one my mason jars for a glass as well!

Perfect solution With plenty of 4oz mason jars at home already, the DIY Kit was perfect for us. It had everything we needed for a successful bottle feeding experience when baby started daycare. The silicone nipple is the most closely-shaped to the breast that I've found, and that is also soft and pliable. The caps keep The nipple clean and also prevent the possibility of any leaks. The sleeve is great for preventing slippery fingers from dropping the bottle, and for protecting baby's sensitive skin from the warmth/cold of the bottle. They are so versatile - we've just begun solids and being able to use the same jars is fantastic. We love them! I've been using them for 6 months now and just replaced the bands last week (I'm guilty of using the dishwasher and not drying immediately) The Mason Bottle and DIY Kit has been the perfect solution for our family.

Excellent Quality I did lots of research into the best glass bottle and kept coming back to The Mason Bottle, and I'm so glad that I did! I love the ease of use, everyone has Mason jars on hand! And the natural, wide nipple. The products are high quality, easy to clean, and I love the color!

Only the best By far the best simple baby bottle out there! Easy to clean super cute design! I have the 8oz and 4oz! Thanks a bunch:kissing_heart:

My favorite bottle solution! I received this set as a gift and purchased another before my baby arrived. It's all I've used since then and I LOVE the Mason Bottle! I wish they had been around when I had my other 4 children. They are easy to clean. The silicone sleeve keeps the glass jars pretty safe. I actually dropped one out of my shopping cart onto the asphalt parking lot and it survived! I get questions about it almost every time I go out and I love sharing how affordable glass bottles can be!

Educating parents one bottle at a time! As a child care provider, I was looking for creative ways to help educate new parents on the dangers of warming bottles of breast milk/formula in the "toxic plastic". Now, as shower gift's, I give them 4oz and 8oz cases of mason jars. Everyone loves the idea and I 'm happy knowing that I helped a little one get a great start in life.

Perfect Gift for New Baby When we were expecting our 2nd baby the Mason Bottle DIY Kit is the only bottle I bought. As a breastfeeding mama, I love that I can store my milk in mason jars - which I think is the eco-friendliest and safest way to store it, and then serve it to my son from the same jar. The kit is so simple to assemble and my son really does love the nipple. Plus the silicon sleeve actually works! I've dropped our bottle a couple time son our tile kitchen floors and no chips or cracks. But the great thing about the Mason bottle is even if i did break the jar, I don't have to go out and buy a fancy replacement. I just need to screw the nipple onto another jar. This is truly a great invention!

LOVE! We LOVE mason bottle products. Both my breastfed babies transitioned perfectly to this nipple. And my toddler loves using the mason jars as a big girl cup. We use the jars for food storage, milk storage, drinking glasses, and a bottle...of course. I'm really hoping for a sippy cup top to come out soon :)

Great value I love using these with my guy! Excellent value and allows some flexibility in what bottles you're using.

Awesome I can't say enough good things about the mason bottle diy kit! Perfect for travel, perfect for my sons little hands, just amazing! Love that i can reuse the jars too once he outgrows the bottle! The only thing missing would be a sippy cup nipple for transitioning!
