Just your average milk storage bags but they definitely do the job. They keep the milk stored and cold in the freezer   

These did the job! I felt like they were a good price and easy to use. Compatible with any type of pump, really.

No leaks, seal tight. Work well for refrigerating or freezing. A great improvement would be for them to be self standing for filling.

Great product! Easy to use and write on. Very affordable it’s not pricey at all. Holds milk well. Seals wonderfully and easy to pour out.

These are simply the best I’ve ever used ever no leaks no nothing very worth the by swear by these r magic

I really like these storage bags. Depending on your pump you can pump right into these bags. Definitely worth trying these out.

Easy to use and easy to store. They take up little space in the freezer and seal well with preventing freezer burn

I love these. Have never had a problem with leakage so far. They work well and fit flat in the freezer. 5 stars!!

Holds plenty and saves really well. I can easily store a ton of these when I stand them up straight in the freezer!

These were the only storage bags I used when I pumped. They're fairly priced and super easy to use and freeze milk with!
