Product Description

v
v

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.

Plus: Our system is flawlessly built into the top of the nipples, so no special tubes, collars, bags or extra pieces needed!

v

100% Made in the USA

Being made in the USA means that we have 100% certainty that our factory is using the safest, best quality materials available.

We know that all our products are being made in a clean environment that meets the highest standards around.

v

Easy to Clean

All components of the DIY kit (and your jars!) are top-rack dishwasher safe! No dishwasher? No problem! The wide mouth design allows for easy cleaning with no brushes or extra tools needed.

v

Feed With Confidence

Silicone is naturally free of BPA, BPS, and phthalates. It is also much more heat resistant than plastic to prevent chemical leaching.

v

What Jars Can I Use?

No matter the brand, our DIY Kit is made to fit any regular mouth mason jar. While the nipple and cap will fit any size jar, the silicone sleeve will only fit either a 4oz or an 8oz jar.

If you’re buying the DIY Kit, then you already have jars at home, and you probably already know this, but the metal rings and lids on mason jars can rust over time. We recommend hand washing and thoroughly drying your mason jar rings to extend their lifespan.

The Only Bottle with 100% No-Risk Money-Back Promise

We’ve checked the return policies of all the major baby bottle brands, and as far as we can tell, Mason Bottle is the only brand with a money-back promise.

All other bottle brands only accept returns on un-used and un-opened products. But how can you know if a bottle 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.

Our Promise 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 promise.

Best bottle idea ever!
5 Stars
Best bottle idea ever!
I remember seeing these a few years ago. I think it was kickstarted maybe? I loved the idea and was hoping it would actually make it. I was so excited to see an ad for it the other day! My son will only drink regular milk out of a bottle in the evenings so I figured this would be my only chance to try it before he finally weans. It came with the standard 0-3 month nipple. The shape is perfect for a breastfed baby! And it really is the perfect flow for a newborn unlike a lot of other bottles I've purchased. I'll be buying bigger ones for son but I'm definitely keeping these around if we ever have another child. I packed away all the other bottles and the million pieces that seem to come with them, and have simplified my cabinet! I love that I can use the jars I already have and when bottles are done I can continue to use the jars for other purposes. It really is perfect!
