These bags were very sturdy. You can write on them with pens or markers for storage organization. These are a great go to for milk storage. 

Love these bags, just wish there was a more convenient way of pouring milk in without risking spilling it.

Great product for storing milk. Easily stored as it can be frozen flat and also easily can warm milk by just putting in hot water.

Great storage for breast milk at half the price of other brands. Easy to close and kept my breast milk safe for baby.

They are sooooo expensive but I use them like cray while I'm at work so I need em. They hold a max of 9 ounces even though it claims 6.

Very sturdy and very good for storage! I liked the other up and up brands but this brand is so much better ! You need to buy more

These were simple to use pretty straight forward especially on the go. I would recommend this product if you are breastfeeding.

Great quality storage bag. The bags freeze well, defrosts well, and are easy to use. They are also sturdy enough to reuse at least once!

Perfect for storing breast milk once the baby comes! If you lay them flat when freezing they take up less space!

I like that these bags fit on a spectra flange. They are sturdy and do not leak. They are not too pricy either. I would recommend this product.
