These bags worked well for us. No leaks from the well sealing Ziploc top. Price isn't the cheapest on the market but they work great and we would buy again and again.

Safe, effective and great price breastmilk bag. I like how thin yet sturdy this breastmilk bags are, it has zip closure and gave me the confidence that it is sterile as I have to break the seal to use the bag. It can stand on itself when around 100ml of milk is in it. I used to pump A LOT over 2 years time and this bag is the best ones I used to store my excess milk. The write on label is easy to write on. This bag can really be laid flat in the freezer. I would recommend this to any mamas who need a milk storage bag.
