Mason Bottle Silicone Nipples, Two-Pack

We use mason bottles every day! This is a great product.

Love these nipples! Throwing them in the dishwasher is the best! We own 10 now

The mason bottles are great! They are safe for our child. Plastic bottles have thousands of pieces of micro plastics your child ingests as the plastic breaks down due to heat. Mason jars are nice because you can buy a 12 pack of jars for a fraction of the price of a few plastic baby bottles. Having 12 jars comes in handy so your not constantly washing bottles. The jars go in the dishwasher and you have plenty . We started with 4 oz bottles and moved up to the 8 oz as our baby starting drinking more formula. Now we use the 4 oz jars to store the baby food we make. The nipples are easy to clean and come in different flow rates as your baby grows. We love the mason bottles and so does our little girl.

I wasn't expecting to be using bottles so soon but I am having to pump and supplement with formula for my 2 week old. He has been using these bottles at every feeding for over a week with no issues whatsoever- he doesn't even spit up when burping! They are easy to clean and I love that they can be used for other things long after he is finished using bottles.

Love that they go on mason jars!

These are awesome. I couldn't be happier that I decided to use mason bottles. I recommend 100%.

My kids used advent nipples and bottles since they were born.. we started using these mason bottle lids and nipples and we love them! My kids are now 3&1.5 and the trans was so easy! We use the largest cut nipple for thicker .. totally compatible to advent nipples and these are cheaper! And better !!

I purchased these for grandchild that is to be born in April, I wish I would have known about them when my children were babies. What a great idea!!

Mason Bottle shipped my order to the UK incredibly quickly. It arrived safely and was exactly as I'd expected! Can't wait to use it!

The slow flow we’re so slow that my baby took over 30 minutes to get out 4 oz of formula but the medium flow work great.

Love these! Super convenient and easy to use.

I wasn’t sure what the transition would be like for my baby going from a Medela bottle to this. I thought there might be a bit of a learning curve. This is our first day and it’s gone beautifully. I love that the shape more closely resembles a breast. I have noticed that it’s a little easier for me to spell my milk, simply because the opening of the mason jar is larger than my other bottles. But that’s just a learning curve on my part. I’m so excited to be transitioning our family away from plastic bottles and using the mason jars.

Our little one has transitioned into the 6+ month flow nipples and she still loves them! I love them because they're easy to clean and I can use them for snack bottles/cups once she is older.

We switched from using plastic bottles with a completely different type of nipple. My daughter took to these right away and now loves her bottles! This has been wonderful since she was previously nursed and didn't like to take a bottle! Already packing away the old bottles.

Love these I wanted to switch my babe to glass bottles but didn’t want to break the bank so I opted for these and I have to say these nipples have been my absolute favorite out of any bottle I’ve tried. I will continue to order !

Highly recommend! You can tell by that nothing but love was put into all of the baby bottle materials. Right won to the nipples. Don’t second quests! Do it for your baby! You won’t regret it.

Highly recommend! My baby took to this nipples with ease. I will never use any other nipples when it concerns my son.

My baby took to these right away and had no issues adjusting

We LOVE these bottles so much! Thank you for making a great product.

Love that I can use these nipples on my mason jars!!! No more plastic for my baby girl!

We love being able to pop these into the mason jars where we store milk! Bonus that we can reuse the jars later to store food or other perishables! Because they're glass, we can expect to be able to reuse them for future children too! This is such a wonderful idea.

We love them! Glass is heavier so it takes awhile before the baby can hold the bottle on its own but glass does not absorb the fat from breast milk like plastic does. I love the convenience of pumping and storing my milk in a Mason jar and adding the nipple top when needed.

Fit the jar & ring great. A little faster flow than expected, but works well.

A total life saver!

Mason bottles are the perfect bottles for our baby! She had no problem latching, and she has minimal gas, and spit up. We also love how easy the nipples and jars are to clean. Thank you Mason Bottle for making our baby happy.

My mother's favorite My Mason Bottles (which really are my mason jars plus these nipples) are my mother's favorite thing to use when she's babysitting. She used to be very much against pumping and using bottles at all, but she loves how she can pop one of these nipples onto a jar of my pumped milk. If it's easy for grandmothers, it works for everyone!

My LO loves these I am breastfeeding / pumping and my daughter has had no issues switching from from bottle to breast! She loves these, they create less gas’s than the other name brand bottle that we have.

Great for breastfed babies My baby is mostly breastfed, but can pretty easily adjust to this nipple thanks to its shape. We went up to the medium flow right about 3 months, so I've found the design to be well matched to age too. I would say the only improvement I would suggest is to make the nipple a little more flexible.

The best! My baby was having a difficult time adjusting to a bottle. She was also a very spitty baby when we wanted to try bottle feedings. She latched on right away and didn’t spit up much at all after the first feeding. We knew we found the perfect, most natural nipples for her bottle feedings!

Thumbs Up These nipples were really easy for my baby to adjust to, very thankful.

Love these! When I was pregnant with my now 2 year old, I was looking into glass bottle options but was overwhelmed by the options and didn't want to invest a ton of money on a product the baby would hate. I appreciate the affordable option these provide but more importantly, they are durable, didn't cause nipple confusion and didn't leak, at all! I am currently pregnant again and cannot wait to use these again!

Great for breastfed babies The nipple helped keep my baby’s latch open after she was born and still learning how to latch properly. Great shape!

LOVE These are our favorite. We will only ever use these for bottles for our children. Highly recommend

Love these These were so easy for my baby to use. After she outgrew each stage I was able to pass them on to a friend’s baby who is now enjoying using them too. Worth every penny!

Truly tested As a foster mom, I’ve used these nipples with countess babies and they have all taken to them just perfectly!

Love these I mainly breastfeed so I was looking for something that would be close to real. I came across these and I am very pleased my little does well at day care with these bottles.

Well Designed Safe, dishwasher safe (though comes out cloudy, use sponge to clear). slow flow was best when trying to get my baby from EP back to breast after a tongue tie. baby showed he was ready for medium flow at 3 months. All the non-believers love this system!

Neat Product So excited to start using these for our baby! Safe, durable, easy to wash!

Best Ever After a LOT of research, the flex and shape of the mason bottle nipples looked best to me. I mostly breastfed but on the occasion where we were out and about or my husband took a night feeding, my son took to these without any problem. From week 1! There was zero nipple confusion. In the future I will probable pair these with the silicone cup so that I can squeeze out any air. Love love love the mason bottle line!

Love them!! I absolutely loved that I didn’t have to buy expensive bottles that would only be used for a little while. We just purchased the nipples and used the 8oz and 12 oz mason jars we already had. Baby boy loved them and I loved that I still have my jars. Thank you for this genius idea!

They’re great! My son is mainly breastfed but takes a bottle while I go to work. This is the only nipple I can get him to happily take. It’s perfect and all you need are the mason jars to pair with it!

Great Nipples Love how easy these are to fit into any Mason Jar. I had a bought a bunch of mason jars but I was usually plastic Avent Natural bottles at first with my son. When I needed to go up in size, I decided to try Mason nipples. My son adjusted great to them. I love that I can just put my mason jar right in the dishwasher to clean! And I already have so many bottles!

Great wide base nipples These are great for breastfeeding babies. We also use these for our older baby when he started drinking bone broth. Our nipples have held up for 2.5 years so far!

Love these! I nurse and pump with my newborn, and she has had absolutely no trouble with these nipples. They don’t cause any gas and are easy to wash. Highly recommend these to anyone looking for a healthier, US made, bottle.

Love the design! My child is nursed, but we use these nipples for when he gets pumped milk. Those feeding my child do not report any issue using these nipples. They secure to a metal ring or Mason Bottle's plastic ring without any leaking. He has a good latch to it and I feel the shape replicates a breast. There has been no nipple confusion.

Love these I love your idea here! A bottle that fits my style and my son loves them. He's never spitting up after feeds and there really are no air bubbles. Side note : Your branding is fun and i love your photography too. Thank you! Keep being innovative!

Slow flow nipple Slow flow works great. I am breastfeeding and was concerned that the flow might still be too much for my 3wk old when I needed to pump her a bottle. I was pleasantly surprised when she took so well to it. There was zero nipple confusion and the flow was perfect!She used the bottle and latched perfectly for her later feeding.

Couldn't be better I used these nipples on Mason jars I already had,and I couldn't be a bigger fan. They are amazing clean easy, baby preferred them, and have a great fit, in top of that they are cute as sin, I just weaned my daughter and I kept these because I couldn't stand to throw them out, if I ever have another baby I'll use them again. If I don't have anymore babies I will give them to someone who does cause these will last a long time I used them for 6 months with my oldest and a year with the baby, still perfect shape. Just always dry the metal ring and you won't have rust, but if u didn't het rust it's not gonna hurt anyone and they are cheap to replace. Oh and u can get stainless steel too! I prefer the stainless or metal over plastic, their silicone sippy tops rock too I'm using those daily now .. thanks Mason bottle u had a great idea and made it work perfectly without all the fuss, they really are the perfect bottle.. oh yeah and I use the jars for sippy cups, food storage, canning,adult drinks snack cups ECT ECT, very handy to have I've always loved my Mason jars and this just made them even more useful

Perfect! Work great, fits regular mouth jars perfectly, easy to clean. I hated the idea of buying a bunch of bottles and nipples, we are on the "crunchy" side and try to minimize our waste. I'm so glad I found this company, and even happier that my son took to these nipples so easily.

Love these! I love mason jars and hate single use plastic. So when I learned that I could store my milk in 4oz mason jars and then easily pop a silicone nipple on it, I was sold. I also don’t have to worry about what chemicals might be leeching into my son‘s milk since no plastic touches it. Clean up is easy, I just toss the jar in the dishwasher and hand wash the nipple. However, the real test is your baby. This was the first and only bottle we offered him, and he took it the first time offered. He did swallow air at first while figuring out how to latch, but that actually wasn’t the bottle’s fault but was a learning curve for us of how to give a baby a bottle and how to position it in his mouth so he had a good latch and seal. Eventually he figured it out as did we and we can’t imagine using any other system!

exactly what I was looking for! We ordered a pack of 2 nipples and we love it so far! My son has taken to them right away and its so nice to be able to use mason jars which we already had at the house!

Love I love them. Ive been EBF an our daughter seems to have adjusted well to these. Going back an forth. I'll definitely be back for more of these products :)

Love, love, love this company and their products I had an issue with one item I purchased but they took care of it right away and everything else I have gotten from them have worked amazing. So glad i chose Mason bottle.

Fantastic My 9 month old doesn't use bottles as we EBF so finding something was quite the task. She loves these nipples! We use mostly for smoothies and they work perfect!

Love! We've been using Mason Bottle for 4.5 months now and have used two different nipple sizes. Our son loves them. We never even had to try a different brand because he took to these immediately. The only "issue" we've had is that sometimes the vents get stuck closed, especially in the 3-6 month nipples. No clue why. And they're easy to fix, but it can be annoying when it happens as it prevents the milk from.floeing as it should. Otherwise, we LOVE these!

The only nipples you'll need My newborn took to these silicone nipples immediately so these are the only ones we need. Talk about simplification! They're easy to wash, durable and their compatibility with mason jars means essential fats and nutrients won't be lost to the bottles as is the case with plastic bottles. Thank you for creating your products!

Five months and counting... I started using these nipples when my daughter was around 4 weeks. She continued to breastfeed without any confusion. She’s five months now and has moved on to the next flow. I appreciate the quality and ease of use of the product. Would definitely recommend to others.

Great flowage Perfect flow rate for my 6 mth old doesn't choke him up<3 always breastfed had trouble this third time around and these have been perfect!

Best flows for my growing boy Nipple flows are perfect for every stage baby latches perfectly its best go to nipple...

Best Bottles Ever! These bottles are legit the best bottles.... and we've used a lot of bottles! Glass and silicone are much better for baby than plastics - that's just science. They're also affordable and the glass is reusable for other things after the bottle phase. But the nipple is arguably the most important part of a bottle. And the Mason Bottle nipples are shorter than a lot of other brands making them easier for bottle-shy babies to navigate. My 6mo has had several obstacles in her short life (she has GER and is very gassy) and has used the newborn nipples, the extra soft nipple (still in testing but Mason Bottle was generous enough to let me purchase), and the thicker liquids nipples and it's clear that the shorter nipple with wider base has made a huge difference for her ability to take a bottle. I rave about these bottles to all my mom friends and the lactation consultants that I've met along the way. Not only are they minimalist, they're also great bottles.

Love them! I love using these Mason Bottle nipples! No problems. My experience has been great. I received my order in a reasonable time and liked how I could receive text messages to get an update on the shipping status of my order.

Fits Lovely My baby has not arrived yet to try these but they fit the mason jars perfectly. I love the look of the nipples. Can’t wait to try these out!

Nearing the end of bottles My daughter is nearing the end of her bottle feeding days and I only recently discovered the Mason Bottle products. I really wish I would have known about these sooner (especially for the breast milk feeding/freezing perk of less container transfers since I exclusively pumped). I am impressed. I was concerned with her taking the shape of the nipple but I guess at this point in time she isn't bothered by it. The vents don't leak! The bottles I have used since she was born always leak out of the vent hole no matter what I try. The highest flow nipples are the ones I purchased and she seems to be drinking a little slower than what she was with the previous bottles' nipples, but honestly, she's been burping less. Oh, and so far she hasn't bitten through the nipple!

First Time Mom We knew we wanted to raise our daughter on glass bottles (along with breastfeeding) but we didn’t know what bottles to choose from. We were scared of nipple confusion and/or her not taking bottles. Our daughter took the MasonBottle Nipple right away and she definitely isn’t nipple confused. I highly recommend these bottles to everyone!

Amazing, durable product! These were the only bottles we used for my son. I was looking for alternatives to plastic bottles before he was born and came across Mason Bottle. We get compliments almost every time we are out with our son! And of course we can't recommend Mason Bottle enough! We are expecting our second baby any day now and will be raising him/her on Mason Bottle, too! Thank you for an amazing product! Looking forward to the Toddler Tumbler!

In love! These are seriously amazing! We use mason jars at home for ourselves so the fact we can now let our babe drink out of them too is a huge bonus! Soooo good.

Great! I was lucky to find out about these mason bottles when I was pregnant so I bought the DIY Kit and some extra nipples. I am so happy with my purchase, they are good quality!

Love this product! I didn't find the Mason Bottle system until my little one was 4 months old and wish I would've found it sooner. I am so happy with it. These nipples work perfectly.with the bottle system. Have had no issues and plan to purchase more for the next stage. Thank you for a great product!

for the crunchy/frugal family Love these bottles so so much! I already had a few 4 oz jars and lid rings in my stash. So I ordered several of these 2 packs and just a few of the plastic lids. Definitely the most economical way to go. My 5 mo isn’t holding (or dropping!) his bottles yet. So we were able to save money on the silicone sleeves for now. This two pack is the way to go for sure!

Lifesaver! Since the moment I found out I was pregnant, I started searching for chemical free baby products. We don’t warm or even store food in plastic so I knew I didn’t want to feed my baby out of plastic. The thought of putting breastmilk in plastic bottles or bags made me cringe. i registered for a few glass bottles but wasn’t most excited about this one. When I went back to work, this is the first nipple we tried and the one she loved. We’ve used them ever since. she has now transitioned to faster flow nipples. Still ❤️. I recommend these nipples to everyone!! I am super excited to try the tumbler when it’s available!

Amazing!! These nipples were amazing they were one of two nipples that my breastfed baby would take until we switched to a sippy cup. He took these with my nanny then switched easily back to the breast when just with me

true wide base The extra soft nipple was the only nipple my breast fed baby would accept. There was no nipple confusion with breastfeeding, able to transfer between bottle and breast without issue.

Best value I ordered extra bottle nipples and I was able to use this product the most since I went back to work and there is always a need for a clean nipple. I recommend This product to all my friends, honestly. To top it off, omen of my fast flows came with a leak and the company quickly sent me a new nipple, no hassle!

Worked for us My daughter is breastfed and I decided to go with Mason Bottles when I went back to work. She has had no problems using this nipple and easily took to it. So glad it worked for us.

BABY MUST HAVE! These nipples have been absolutely wonderful! I highly recommend them for any parent who values high quality eco friendly USA made baby items. These reduce the overall amount of baby items we need for our son. Our son is adopted, so we exclusively formula feed and have used these mason bottles for several months! We love them!

Love this! I store my milk in Mason jars. Having these cuts down on the number of other bottles I need. Saves space. Air vent is good and it seals well.

A Year with Mason Bottle Nipples! A few weeks before the due date of my first child, I read about Mason Bottles. I LOVED the concept! I wanted to use glass bottles, and the fact that I could use mason jars (which I could also use for other things) was definitely appealing. I had been told by many mom friends that babies often have to try several different bottles, some refuse the nipple, etc. I had NO issues at all introducing the bottle to my LO when he was 4 weeks old. He is turning a year old next week and I have nothing but praises about these nipples. Thanks for a great product!

Love! Love these. They are so easy to use with my Mason jars and what's even more awesome is they are so easy to clean which other bottles weren't and I was fed up but these are so easy wish I had them from the beginning!

Excellent! These are sturdy, yet well vented. They do not leak!

Perfect! I love these bottle nipples! They fit perfect with the mason jars of course but they also are amazing if you are also breastfeeding! They are also really great about being anticolic! They really are the perfect ones for me and my baby :)

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!

Easiest baby bottle ever How amazing is it to buy a $1 jar at the store and slap a nipple on it and have an amazing baby bottle! My girl loves this! It's sometimes hard to get a breastfed baby to take a bottle but my little girl took this. :D

Good to have on hand.... I purchased the Mason bottle kit and extra Mason jars from the store. The extra nipples are good to have on hand. Less dishes. No scrambling to find a clean one when needed. They are a little pricey but so worth it!

Great for breastfeeding!!! My daughter REFUSED every single nipple we tried. She took these without a problem and had no issues going back and forth nursing!

Love these! I'm so glad I found these! I love that I can use mason jars I already have, and that I can store milk and feed from the same container. These really do simplify my routine!

Awesome! I am so glad we found these for our family! Could not have asked for a simpler way for my husband to feed our son when I have to be away.

Wish I knew sooner It wasn't until my son was about 6 months old when we discovered these AMAZING tops! We had spent so much time and money on all the other bottles on the market....seriously, ALL. My son was bottle fed since week one since my supply was so low and my husband created a formula alternative we lovingly called "Daddy Milk" filled with supplements and fish oils. Because of daddy milk we would scrub the other bottles forever then boil them to get them super clean to help them not maintain the fish smell. Needless to say we went through a LOT of bottles that loose their integrity over time when boiled. We were already mason jar believers using them to store nearly everything in our fridge and freezer so finding these tops made our lives so easy and happy and fun! I have since bought 5 sets of the fast and fastest flow (also great for daddy milk supplements to flow with ease) and two of the silicone sleeves to avoid breakage. Don't waste your money on any other bottle ever. You found the PERFECT one right here.

Awesome product. I love that I can have a stylish, simple, plastic-free bottle for my baby by just using this nipple with jars i already have!

Work great & fast shipping! Recently ordered some extra nipples because our son is starting daycare, and they arrived quickly and have been working great!

Great for premies! My baby was born 1 month early and spent 11 days in the NICU. While I was waiting for my milk to come in, I used donor milk. I had bought the mason bottles before baby was born, but was unsure how he would take to them. After a few tries, my very sleep, jaundiced baby was drinking the whole 4 oz jar! Now, 3 months on, he still loves drinking from the jars (I pump and supplement with formula). I receive many compliments about the jar when I use them. They are also so easy to clean compared to other Baby bottles and I sterilize them by boiling in the morning everyday. I am so happy with the mason bottles! Love them!

Wish I Would Have Switched Sooner! Just bought these and the sleeves for my 10 month old and I wish we would have found them sooner! I could have saved so much money and hassle by using just mason bottles since birth. The concept is brilliant! Good for baby, your wallet, and the environment. Couldn't ask for anything better. 5 stars!

LOVE these We adore these nipples. Our daughter has used them since birth and we couldn't be happier. We love that they allow us to use mason jars since they're so versatile and will have many uses as she grows; bonus is that I store my expressed milk right in the mason jar in the fridge and freezer so I don't need to buy milk bags and can go straight from freezer to warming water to baby without a big mess. I also love the quality of the nipples; we've been using the same two nipples for 9 months now (she doesn't seem to care that she's still using the slow flow nipple) and they are still holding up great. I tell everyone I can about these because I love them so much!

Best Nipple Yet - As Close to the Real Thing The nipples are very wide, like on an actual breast, and our daughter really likes them. On the occasion that we use anything else, she plucks at them, or chews on them. Early on, before she was able to really communicate with nuance, she would suck really hard on the other nipples and make a very strange noise. As soon as we changed over to these her feeding became effortless. (We use the FAST FLOW (6+ MONTHS) - and intend on moving up so she can eat smoothies). *We use the 4oz and 8 oz Ball Quilted Crystal Jelly Mason Jars - though as long as they have a Regular Mouth ring, you can pop a nipple on them and voilá. *The nipples are higher priced than most. They are made from a high grade silicone however, and when I called Mason to enquire about the pricing, I was told that because they were manufactured in the USA, they were stricter on their standards and quality, thus driving up the price. They are well worth it though.

Awesome!! Spectacular- and SO cool!!

New Mom loves this! I gave a set of these to my friend who is a new mother. She collects unique mason jars so she LOVEs these.

Perfect for Breastfed Babies As an exclusively breastfeeding mama, I was nervous about finding a nipple my son would like when I went back to work. I'm happy to say that the shape of this nipple is perfect for breastfed babies and fits perfectly in my mason jar lids. If you can only buy 1 bottle, this is the piece to invest in since you will be able to make 2 great bottles for only $10!

Excellent purchase I bought these during kickstarter campaign time. I have loved letting my little guy use them & plan to buy more for my second babe due soon. Highly recommended.
