Good quality bags. Don't leak, and thicker plastic so they don't tear. It also has 2 zips on it to keep the milk fresher. I got a box of 100 at Walmart for $10, worth the money. They last longer than you would think

Love these storage bags. They don’t leak, they hold up to 6 ounces of milk, and you can stand them up or lay them flat in the freezer. They are more pricey than some other brands but they are worth it. Highly recommend!

These bags lay flat for easy storage and, in my experience, have yet to leak. Unfortunately, I have found that they are not a true measurement and do cost a pretty penny more than other brands with similar quality.

These were my favorite great milk bags. They were very soft so they moved easily and were easy to out milk into. They have ounce lines on them for easy measuring too. I love how they say my mommy's milk on them too

These bags are so easy to use. They have a double seal and I’ve never had one leak. Milk can be frozen flat or you can open the bag to stand on its own. These are a great value and a necessity. Keeps milk fresh

LOVE these!!!! Super cheap option to store that valuable breastmilk! Super easy to pour the milk into so you're not wasting the milk spilling it all over! Only milk storage bags I use and probably will ever use unless something changes!! These are the only ones that are in my freezer!

I love these bags. They are easy to use, open, and lable. They hold about 5 ounces of milk. They do not leak and you can freeze flat. The only con is that the measurments on the bag are not that accurate.

These are the best milk bags I have tried so far.  I have yet to have a leaky bag and they are easy to write one for noting date/amount. I also like that the place to write the date/amount is on the top above we're the milk goes so there is no risk for puncturing the bag.

These breast milk storage bags are so great! They are perfect for me because I can drop off my daughter at my mother in law's while I go to work and I never have to worry about leaving bottles there.

I’m on my second 100 count box. I had no problems w/leaking, spilling or breaking. I’ve thawed out milk in the fridge & milk warmer.Reviews have mentioned spillage but I do not agree. Highly recommend.

What is the best way to thaw these for use? I have been building up a good supply in the freezer for when I need to use them.
