Product Description

I ordered this cap made for the metal mason jar ring, thinking any standard metal ring would work. However this cap does not work with the metal ring I have (Mason Jar Lifestyle brand - stainless steel). On the box that the cap came in, it states that it's compatible with only the "Ball Brand." No where on the website did it say this (that I could find), which is misleading.

My daughter and I both love this bottle. Easy to clean easy to switch out nipples and caps and because my daughter is picky about her milk temperature I love that the milk stays warmer for longer in the glass jar. Great product!

These snap nice & tight. I am confident that they are safe to store in the fridge without contamination & not spill in the diaper bag.

Best Decision. It was the best decision to buy these mason jar bottles. I love them. When my boy is bigger I just keep them. To put money in the bottles for his 18th birthday to make him a box with special things like these bottles.

Good Product Good fit, keeps the nipple clean, centered. Good for traveling or diaper bags!

Grace Ross

Great and snug Once you get the hang of it, these work great! I found of the nipple wasn’t exactly centered when you snap the lid on, it would push the nipple to the side and milk would leak more easily. BUT if once the lid is on you give it a little turn to the right, the nipple will center and be sealed with no leaks. We used these all the time!

Secure fit When ordering, I was worried that it may not have a secure enough fit for traveling/ sending it to the sitter/ etc. without spills and such however, it fit much more tightly and secure than I imagined. I was very happy with it!

Kristina

Great covers These work great on your mason nipples, as well as the straws! Sometimes it’s difficult to snap on, but once you get it, it covers the bottle well! Worth it to get a few when traveling!

Get for Travel Love how these caps fit so securely. We are on the go with working full time and these will work perfect to contain any spills that may occur.

Stephanie

Great for on-the-go & babysitters! These caps make transporting bottles a breeze! I also use them to have bottles prepped and ready to go in the fridge when we have babysitters so they can grab them and warm the bottle without a hassle...so easy! They fit perfectly! Really happy with the whole Mason Bottle system! Thank you!

Fits perfect, great for bottle warmer These fit perfect with the nipples and any mason jar. We use these when we warm a bottle in the Kinde - works just like we need!

Keeley

Fit Well These fit well, a little snug. It's nice to have the option if you want to premake a bottle for the fridge or store it. Though I nurse little one while we're out, I see the cap being helpful for daycare and traveling.

Great fit! This cap is so great for trips on the go. Fits our mason jars beautifully and the design can't be beat. We love them!

Annessa

Work great! These caps fit well on any regular mouth mason jar. They stay on, and keep the bottle nipple from rubbing on everything in the diaper bag. Love them!

Amanda

Great fit Perfect fit for the mason bottles. Doesn't come off and makes travel easier.

Sebrina Parker

Perfect Fit There is nothing worse than a bottle cap that pops off too easy or totally leaks (I'm looking at you MimiJumi). I was a little nervous how this cap would fit considering it's made o be a universal fit for any old mason jar. Well this cap works! It securely snaps on to all our jars and keeps the nipple clean and leak free when I throw a bottle of milk in my bag :)

Fits Tightly Over Regular-Mouth Mason Jars

We developed this cap to snap securely over the metal ring that comes standard on most mason jars in the US (Ball + Kerr Brands)

The cap will snap on very tightly to make sure no milk is lost in transport and the nipple stays squeaky clean.
