Mason Bottle Silicone Nipples, Two-Pack

Fit great with the plastic lid rings. Took me a minute to get it placed correctly without pulling it through, but once I figured it out, it was easy. Love that they don’t leak and little man latched right on!

This was a reorder of a product that we’ve been using for the past six months. We needed more and have loved them all.

My baby was exclusively breastfed from birth so I wasn't sure how he would do transitioning to using these. At around 10 months old he wasn't quite getting the hang of it at first but then did figure it out. He's 1 now and easily drinks from these. It's so convenient being able to give him milk or water straight from a jar. Cleanup is so easy and I appreciate the sustainability of the product.

We've been using these mason bottles/nipples for nearly 4 months and just moved up to a faster flow nipple. Our girl loves them! Our daycare also thinks they're a great option, and it feels great to be using glass for all her meals. We've happily recommended these to all our friends with babies.

So great!

Great quality and nice flow for a 11 month old baby!

Our baby loves these bottles and I’m so happy that they are glass!

I really like the mason bottle product, I love that they fit glass Mason jars and how easy everything is to wash. My only issue is that 2 of the slow flow nipples I bought had issues. One leaked from the built in vent and made a huge mess every time it was used and another one didn't work at all, nothing would come out of the nipple, even after I tried piercing it with a needle. I ended up throwing both away out of frustration, when making a bottle for a hungry newborn I don't have the patience to fiddle around with nipples that don't work. I'm sure it's just a manufacturing issue, but out of 10 nipples 2 didn't work...

These nipples are Sam's favorite, along with our dog, Prim as well!! She loves to snack on them of bottles have been inadvertently left out while putting Sam either to bed or down for a nap! That is why I had to reorder them!! I highly recommend this whole line of products. I love being able to use the nipples in conjunction with our collection of mason jars.

Perfect! Exactly what I was looking for. I can't wait to use it with my baby when it's born!

Love mason bottle products! So many great uses! Love that they're dishwasher safe too!

Perfect fit for my regular mouth mason jars! I’m excited to try it out once baby arrives.

Nipples are great! Love the cute little heart anti comic cut outs.

My son was having a hard time with gas and spitting up he was also choking when eating sense I got these I bought 1 pack to try them. My son loves them gas problems almost nonexistent and he doesn't choke anymore. Currently using the slow flow but have already ordered 3 boxes of the next size as well when I placed my second order.

I love these bottle nipples! They’re great for my kiddo and he loves em. I love using a mason jar for his bottles.

High quality nipples and they can fit on most size mason jars! They are absolutely wonderful. I think when baby is done with them I will use them for pickling haha

This nipple is almost the correct flow.. It's still a bit fast but we are working on it

Both my baby and I love this product! It’s also very easy to clean, which is a big plus

Works great, simple and so so much easier to clean and store!

They're great. The shape is great, they don't collapse too easily with too much suction, they are actually slow-flow (some nipples say they are, but really aren't - for these ones, it's true).

Great bottle nipples. My daughter goes easily between breastfeeding and the bottle using these!

Amazing invention! I wish I would have thought of it first! I have been recommending this product to all my friends at church. Two girls are converting to Mason Bottle in the one week I have told them about it .

Fits perfectly with all my other mason products

Very cute and fit perfectly with the rest of the mason products I ordered

Mason Bottle is a really innovative, eco-friendly and quality product! I'm a new mom of a 3 month old boy, and this nipple is very close to the real thing, so my son loves it! Way easier to clean than the bottles the hospital gave me, which he refuses now (or confuses?) Also, you can choose jar size zee and flow to suit your needs. Customer service has been amazing too, comping me when I forgot to use a discount code.. 100% would recommend Mason Bottle!

My exclusively breastfed baby had no problem latching onto these nipples when we first introduced bottles. These are by far our preferred bottles in the house.

Work well. Good flow rate. No probs using these in the silicone bottles or my mason jars!

Work perfectly with standard mason jars and rims. Love that I can use my canning supplies for bottle-feeding my little gal. Excellent products!

For my sister

I love this system for bottle feeding my baby but because my child is mainly breastfed this slow flow nipple is still way too fast. It would be really awesome if you could look into designing a “preemie” flow nipple. This works so well for breastfed babies who have to switch between bottle and breast. Since they have to work harder at the breast to get milk a slower flow nipple makes them work harder and makes transitioning from breast to bottle and vise versa so much easier. Just as an example Avent has a preemie flow nipple size 0 which is slower than their slow flow size 1. This nipple flow works wonders for breastfed babies, and for that reason I love using avent bottles and nipples. But I love the concept behind mason bottle and the minimal waste associated with them. So I just really wish you would look into developing a “preemie” flow nipple.

The bottle nipples work good

The baby isn’t due till August. Bought these for my granddaughter as a shower gift. She will love them, I’m sure.

Love it

Great bottle feeding system. No leaking issues!

Great system for having a plastic free bottle option for my baby!

This product arrived on time as expected. Will update with a better review when little one is here and tests the nipples out.

I ordered the 3-6 month silicone nipples to go with the mason bottles I purchased but my son seems to struggle using these nipples. I believe the silicone is a little too thick, which is why he struggles to eat when using these. I’m going to give it a few more attempts before I give up on it completely. I still hopeful that these will work out for him.

My grandbaby is formula fed. We were using bottles that have the drop-ins. Didn't want to buy more drop-ins, so we whiched. Love these bottles, the nipples are ok. They are a little short and the grandbaby well fight with it. Would be nice if there were longer nipples. We already had (a lot) mason jars, so this was easy and cheap.

We love mason bottle! My older kids love the silicone straws as well. I love that I can use our regular drinking glasses for the whole family with just a small modification. We've saved so much on not buying baby bottles that get used for a short time.

I’m loving the simple setup of the Mason Bottle. I ordered every size nipple and the metal band cover. That should get me through the whole bottle feeding experience! The 0-3 month nipple is particularly great. My daughter took to it immediately. It has a wonderfully slow flow that kept her from chugging. The other plus is the shape of the system. Because the nipple itself is wide enough to fit a jar, the nipple is more similar to a breast than other bottles. Her latch was much much less affected—as in I don’t notice a change at all.

These nipples are perfect! I love the quality the mason bottles provides!

Work well with regular or bought here glass jars

I love that I can use my own jars making it much less expensive than other bottles. The flow rate for these bottles was just right for my newborn much better than other bottles I tried that had a faster flow.

Works great!flow is perfect!

My exclusively breastfed baby had no trouble using this—apparently it’s pretty close to the real thing! I used the slow-flow for the first few months and then switched to flexible flow.

My granddaughter transitions easily from the breast to these!

Good size, and well vented.

My son and I love these bottles! I have several nipples but bought another set of the 0-3 months so I could have extras since I am exclusively pumping now. There was a defect in one of the heart shaped vents in this order and it was leaking but customer service was excellent and they are replacing it. Cannot brag on this company and their products enough!

Not loving the new nipples. It seems to be leaking out the valves when we shake up the formula. It's really become quite annoying as it leaks out the lids onto our hands. We didn't have this issue with the 0-3 month nipples. Any suggestions on how to remedy the situation would be very appreciated! Thanks

I am loving all of the Mason Bottle products! My daughter has been using them since she was 2 or 3 months and I recommend them to everyone

Only nipples we have used! So easy to use and I love that I can use them on any size mason jar!

The item I purchased was a gift. I hope they will like it.

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
