Love Mason Bottle. I freeze my excess breastmilk in the jars. Super easy to defrost the jar and pop on the nipple attachment. No need for bags or transferring milk from a bag to a bottle. Love that their dishwasher safe too.

Very happy with Mason bottles, our baby loves using both the smaller and larger sized ones. The larger opening makes it very easy to clean and to mix in the formula.

We LOVE our mason jar bottles ! They are our favorite from having multi different uses. They are by far our family favorite

I broke a jar in the beginning of the baby experience and needed milk storage. They were able to quickly replace the broken jar and answer questions I had. This is a great reusable/sustainable milk storage solution.
