Big, inexpensive, works well, but sweats a lot.  Box indicates there was a cover (says not to use it without your own or the covering provided) but it does not come with one. Bare skin on it would be too cold. It seems to stay cold long. You can fold and unfold it frozen or thawed (fold in half and then once more in half).  I don’t heat these I use electric pad for that. I don’t trust gel type pads in microwave after leaks and fires with other products.
