These are ok like anything Liquid you put into a bag it could spill but these are hot to bad these actually hold pretty well! Good for freezing milk right away

Work perfectly fine. Freezes flat. Easy to use and write on. I wish these stood up on their own. It's nice that a lot come in a pack and are affordable.

I loved these bags with my last baby, we don’t currently use them with this baby because she does not like the milk after it is frozen. But, they were great bags when I did use them and I never had any issues out of them.

These bags will get the job done for sure! I haven't tried many types of storage bags for milk so I may be uneducated in this field but these came highly recommended and they are doing everything go need of them!

I love these bags! The double zipper means no leaks and keeps milk fresh in the refrigerator or freezer. They are also easy to pour into a bottle thanks to the "spout" on the bag.

I didn’t have Lansinoh pump with either child but this storage bag is the one I preferred above any other I tried. The design makes for mess free pouring into a bottle. I lay flat to freeze for more compact storage.

These are my favorite bags, they store super flat when completely full which makes storage much more efficient and they thaw quickly, which is very important for us

I absolutely love the Lansinoh Breastmilk storage bags. They are so easy to use. They are nice to write on and I also like that they freeze/store easily.

I couldn’t live without these bags! This is my second child and I learned with my first pregnancy that these bags were the best! I’m a month post partum and have already gone through a whole box!

I have tried sooooooooo many brands of milk storage bags. Some of them leak or tear easily or don’t sit right in the fridge and freeze but these don’t have any problems for me. I continue to only buy this brand now and definitely recommend.
