I really wish these caps were better. They don't fit in my bottle washer when attached to the ring so I have to take them off or hand wash them. After 2 times the attachment part breaks. For what you have to pay for one they aren't worth it.

This was a perfect addition to the gray plastic rings as we were struggling to use these bottles when out and about- tried the metal rings, but they rust so this was absolutely perfect. May advise hand washing as one of the caps didn't click tightly after using in the dishwasher. I'd advise not clicking the in the hinge when bottle feeding as it's nice to be able to remove the cap while feeding. Thanks so much for making these! We love them.

We love this item! It helps make sure nothing leaks out of the bottle and helps keep the straw from getting dirty!

I was looking for a system for our newborn that was multi-functional and simple. We took a chance on Mason Bottle on the recommendation of a fellow first-time mom, and are very pleased with it.

It will help us travel well without more mess! Fits perfectly with jars.
