## Customer Reviews

### ⭐⭐⭐⭐⭐ Very useful
*by A***A on March 26, 2025*

Using for breast milk storage, very useful. Tops fit other jars of the same size. I did have one break when I dropped it and one top crack. But they are pretty thick glass.

### ⭐⭐⭐⭐⭐ great for milk storage
*by C***H on March 21, 2025*

These jars are perfect for breastmilk storage. They don't leak and are easy to use.

### ⭐⭐⭐⭐ Good storage jars overall, but room for improvements
*by J***B on January 10, 2022*

Grateful to have an American-made, glass container to store pumped milk in for my baby. The lids and jars are easy to use together and do not leak when assembled properly. Great in the freezer or fridge. Also handy for storing baby food, or any other small thing you might need kept in the fridge.A few downsides…-The jar lids are advertised to work on all mason jars, but it can take a lot of finagling to get them actually sealed.-Before each use the inner ring needs to be pressed fully into the lid; if there is a gap it will leak (would be great if future iterations have silicone inside of the lid instead of 2 separate pieces!).-Due to the 2-piece design, sometimes the separated fat from the milk gets trapped on and under the ring; sometimes giving the jar a good shake before opening gets it all, sometimes not. When it doesn’t, I’ve taken to using one of my baby’s silicone spoons to get it off and back into the milk. Messy and an extra step when there’s usually a hungry, fussy baby waiting for it.-I have used these with the rings and nipples they make as a bottle for my baby. Those are another review (rings leak and nipples are too shallow/narrow for baby to get a good latch), but I found the jars to be frustrating to use this way because they are wide-neck and short, so it’s hard to get all of the milk to the nipple.Overall a good product, though! As baby is getting older and taking more than 3.5 oz/bottle I’m considering buying the set of 8 oz jars, so despite the frustrations they are still the best product I’ve found for the purpose.
