Lansinoh breastmilk storage bags are easy to use, secure closure for good storage, they have a good size and are easy to mark. I love them, easy to clean .

Love how good these freeze and how much you can put in them. These are the best freezer bags. I have only had them leak once out of hundreds of bags I've used!

The bags freeze flat. I haven't had any issues with them leaking when thawing. They are a bit thick compared to others I've tried before. So far I love them

These milk storage bags are just okay. Not my preferred option when it comes to freezing breastmilk because of the closure system. When the milk thaws too pouring from the top is somewhat challenging.

These bags are so awesome. I had over 4000 oz. Saved up in the freezer. I saved so much and never got holes in them. The ounces were super accurate too!

These are very hard to close so I'm scared they could leak my milk that I worked very hard for. They're also super thin and I prefer a more sturdy bag. But they work for what you need them for.

These bags are the only ones I've liked using since day 1 of breastfeeding my twins. The best! The shape makes it super easy to freeze flat and bag up.

I hate these bags. 1. They are very difficult to open. 2. The have lots of extra plastic at the opening, which makes pouring in milk from a pump difficult, and has resulted in spillage more than once. 3. They will not stand up, regardless of volume. 4. The labels are upside down. 5. The bags DO have an excellent seal on them, though, which is why they have 2 stars instead of 1.

I have tried about 5 different storage bags. This bag is by far the best bag I've tried. (I need to thank my buddy again for recommending this!). I love the double seal. I haven't had to worry about leakage with these. Plus, these bags TRULY freeze flat! Used in conjunction with a breast milk storage organizer, I am able to build a good supply for when I return to work AND leave room in my freezer for actual food.

I really like these bags. I have filled them with only a few milliliters up to 6 oz. None have ever broken or leaked. They served us well during my twin pregnancy and now during my baby boy’s breastfeeding journey (almost one year). I can recommend these.
