These bags stored my breast milk fine in the freezer. None of my milk leaked while thawing. I only give it four stars because the label at the top is upside down and there isn’t much space to write on the label.

Love using Lansinoh Breastmilk Storage Bags! Very easy to store flat in the freezer and transfer to gallon size bags to save space. Never had an issue with leaks or spilling.

Have never had any issues with spilling or storage. Super easy to use and then lay flat in freezer. Stickers with ounce amount could make it easier than labeling each bag, but overall use these all the time.

There’s not much to say about these bags! They are very durable, no leakage. Has the volume measure on the bag and a spot to write date/amount/time. They are super affordable and easily accessible at most stores

love that these have a double seal and are easy to get all the air out for freezing. They are thinner and more flimsy than the medela bags but they seem like they will hold up well!

These storage bags made storing and freezing milk so much easier! The plastic didnt smell weird either, which is usually my concern with plastic products. Milk can be thawed while its still in the bag and it just made life that much less stressful

Thanks to lansinoh storage bags, I have now wasted 3 bags of milk. I’m not sure what is going on with these bags but my milk is too valuable to be wasting. I won’t be anything else from this brand.

I really like these storage bags! After cooling my milk in the fridge, I pour 5oz into a bag and press it up against the counter to remove any excess air. No problems with leaking & the writing on the top stays put.

I bought other brands before but this is the only brand with absolutely no leaks after stored in my freezer. Bag looks very fragile but is very sturdy when milk is frozen and defrosted. Highly recommend this brand

I definitely like the bags, they hold milk well and freeze well, and thaw very quickly right in the bag by running under water. However, it can be messy getting the milk from here to a bottle when transferring.
