not good quality.

overall the bag freezing flat is amazing but when going to thaw the bags aren’t so great. I bought them at the very end of February and had just started to officially use them. as im thawing the bags I noticed water actually got in through the seals as well as the bags having mini punctures. Unfortunately Ive had up to 40oz of my breastmilk thrown away since each bag once thawed would get water in it.

Bags too thin and explode

My baby has been in the NICU for a month now, and I switched to these bags recently. Lactation told me my bags are exploding and to change brands. They see this happen consistently with these bags because of how thin they are. I had to throw over half of the box away because I don’t want to keep wasting my milk.

Everrrrrry box that I buy has bags that leak at the seams. It doesn't matter where I buy them from. Seems to be an issue across the board.

Beware‼️

Bags are too thin. I have thawed out a few that had a small slit and leaked.
