These nipples are designed for an easy latch and even easier cleaning—our parents find that the flow control and ventilation system built right into this nipple help reduce colic and gas without any hard to clean (and easy to lose extra pieces.)
One pack of Mason Bottle Nipples can do the work of a whole baby bottle system if you’ve already got jars at home, helping you save space, save money, and save the planet.

Fits Regular Mouth Mason Jars
Breast-like Shape and Flow
The wide design helps ensure a breast-like latch. Our nipples are designed to flow smoothly and smoothly to mimic the pace of breastfeeding.
Lactation Consultants recommend always using the slowest flowing nipple your baby will accept to promote a smooth transition from breast to bottle and back.
Built-in FussFreeTM Ventilation System
All of our nipples are designed with our FussFreeTM Ventilation System. This dual valve system allows air to be taken in and milk to flow smoothly out with no air bubbles to help prevent gas and colic.
Bonus: Our system is flawlessly built into the top of the nipples, so no special tubes, collars, bags or extra pieces needed!

Leak-Proof Guarantee
When turned upside down, a couple drops will come out. This is normal for all baby bottle nipples. Use those couple drops to test that the milk is not too hot.
But once the feeding begins and baby has latched, there should be no leaking—all our nipples and bottles come with a leak-proof guarantee.

Our Guarantee to You
Will My Baby Take the Nipple?
All babies are different, so it's not humanly possible to design a nipple that works for 100% of babies. This may mean you need to try a couple different bottles for your child.
At Mason Bottle, our return rate is 3%, so there’s just about a 97% chance you and your baby are going to love this product.
But just in case you fall into that 3%…we also offer a money-back guarantee.
The Only Bottle with 100% No-Risk Money-Back Guarantee
We’ve checked the return policies of all the major bottle brands, and as far as we can tell, Mason Bottle is the only brand with a money-back guarantee.
All other bottle brands only accept returns on un-used and un-opened products. But how can you know if a nipple really works for your family without trying one first?!
You can’t. So we decided to create a new policy that puts families and quality first.

United StatesFavorite baby bottle nipple
Absolutely love these baby bottle nipples. The shape allows for an almost seamless transition from breast to bottle and vice versa. The slow flow nipple truly is slow flow so baby isnt being choked by milk gushing out, even with his strong suckling reflex. Would recommend this product to any and all parents. Easy to clean
These worked great with our current mason bottles and baby is happy drinking from them. We liked them so much we bought another set and use them every day.
Perfect! Flow is as expected and great for my little guy when I'm not around!
