Little pillows of cold in a convenient, relatively thin, flexible sheet. Use them instead of ice and it it cooler and no wet mess. Have used product for years to keep food cold in lunchbox. Good product for coolers and transporting food.

Water penetrates the white paper side but doesn't leak out ever. Can be dried and used again. Looking forward to drying out and then hydrating for camping and cooler use.

They are almost flat but stay supercold. They are reusable and the strips can be cut to fit your needs. Can also be used for icing swollen joints like an ice bag.

When they begin to thaw, that slimy substance leaks out of it and onto the items the are keeping cold. After it is thawed, it has no odor at all, but frozen it was terrible. These are not the gel freezer flexible packs!

These things leak a horrible goo that i don't want anywhere near the food and drinks i'm trying to keep cold. They start to leak the water you used to hydrate them along with a slimy goo. Also, started leaking shortly after purchase.
