Love these bags! I never had an issue with them leaking or opening. I love the tab where you can write the date and ounces. I would freeze these flat and stand them up for storage, never had an issue. I would definitely recommend these.

This is my go to choice for storing and freezing pumped milk! The double seal prevents leaks with ease and the adapter for pumping directly into the bag worked well with my pump of a different brand.

I purchased these when I first started pumping to start a stash of breastmilk. I was worried after reading some reviews that they had issues with them leaking but after 6 months, I have yet to have an issue. They are also well worth their price.

I trusted this brand to store my breast milk. Very easy and wouldn’t leak or break at all. Very affordable as well. Give this brand a try Lansinoh Breastmilk Storage Bags

These bags are perfect for milk storage! I froze them flat so the could stack nicely in my freezer. Then I could just pop what I needed for the day in a lunchbox cooler.

These storage bags work great. They are affordable, and easily freeze flat. Not really sure what could be done to improve them, they work great for their purpose.

I love having a lot of these. During breastfeeding sessions I have a lot of let down that goes into my suction cup. When I am done feeding my baby I just transfer the let down into a bag instead of wasting it. So convenient.

The BEST! I have used with both of my babies. Never had a problem with holes, leaks, air, etc. I currently have over 1,500 oz of milk stored in these bags in my deep freezer.

These storage bags are great! No leaks at all and freeze very nicely. I also loved how you can pump right into the bag. They only thing I don't love it the measurement is a bit off.

I did like how easy it is to store your breast milk. I like how you can write how many ounces and the date on it. The only thing I didnt like about it, it was hard to fit the bags with my breast pump I got.
