Lansinoh Breastmilk Storage Bags, 100 Count, Baby Essentials, Fast Freeze & Thaw Breast Milk Bags for Baby Bottle Feeding, Superior Strength & Stretch, 6 Ounce

Everything they should be! I pump right into them and they stay secure and don’t leak. I’ve seen many folks say that the lines for how many ounces are off but they’re really not. You just have to make sure that the bottom of the bag is fully expanded. Freeze great.

These breast milk storage bags have been a total lifesaver during my pumping journey. They’re super easy to use, with a wide opening that makes pouring in milk mess-free. The double zipper seal gives me peace of mind that nothing’s leaking, even when stored flat in the freezer. They are perfect for the "brick" storage concept as well.I also love how durable they feel—no flimsy plastic here. The measurements on the bag are clear, and there’s a space to write the date and amount, which makes organizing a freezer stash so much easier. Personally, I like the clear plastic color so I can see any air bubbles or freezing issues.Overall, great quality, easy to store, and a must-have for any breastfeeding or pumping mom. Highly recommend!

I was using the free bags I received from my insurance company but decided given these a try when my bags wouldn’t freeze flat. These freeze perfectly and are so easy to get air bubbles out of.

These are my favorite milk storage bags. They are easy to get all the air out of. They are great quality. The Zip lock is easy to seal. They are very easy to thaw and open.

These are my all time favorite bags to use! The zipper is easy to zip unlike others that are super stiff. They hold shape and freeze well

These are by far my favorite breast milk storage bags. The quality is great, seal is great. You can’t go wrong with these or this brand!

I have ONLY ever used these bags and this time around for pregnancy the bag have broken when I’ve defrosted them. Like I sit the bag out to defrost them and it’s leaking somehow. They have not been touched since going In my freezer so I’m not sure why the last two purchases have had bad bags, but I’ve lost 3 bags of milk which if you’re a mom you know is awful.

I’ve been using these breast milk storage bags for a few weeks now, and I’m really happy with them. They’re easy to open and they double lock seal tightly, which gives me peace of mind that nothing will leak. The material feels strong and doesn’t tear, even after freezing. I also love that there’s a spot to write the date and amount, it keeps everything organized in the freezer.Overall, these bags make storing breast milk simple and stress free, something very important for newborn moms. A must have.
