These reuseable, non-toxic ice packs are unlike the gel-based packs you may have used. Most ice packs on the market today contain urea, a waste byproduct. Instead these packs use a super-absorbant material instead. You can cut them to any configuration you need, soak them in water for a few minutes and freeze. The packs remain flexible when frozen, and they do not release the water once they thaw out
Avaiable from Earth Friendly Finds for $7 per 36.
