Leak when transferring
These bags are great to pump directly into, and are a nice thick material for storage. However they are nearly impossible to transfer the milk back into a bottle without making a mess. The first use, I spilled 5 oz. of milk - hard not to cry over spilled breastmilk! Other brands make far superior, easy to use bags.
ProsPump directly into
ConsPoor shape, easy to spill
Best UsesLong-term storage of milk
