    4oz Jar Only Replacement

    $5.00

    Customers praised these jars for breastmilk storage and feeding, with "easy to defrost" and dishwasher-safe convenience. The wide opening simplifies cleaning and formula mixing. However, multiple shoppers reported receiving broken jars in shipments, a significant quality control concern.

    BROKEN

    The replacement jars for the broken jars I originally received, CAME BROKEN ALSO. After seeing many other reviews about multiple broken jars in orders, I cannot recommend to anyone.

    Great easy option for breastmilk

    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.

    Good customer service

    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.

    Great storage jar

    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.
