It really works!,

I was surprised that this actually works. You just click the little button in it, and instant heat!
The button causes a reaction, and the liquid chrystalizes and is hot.
Then you have to boil it in hot water for 8 minutes or so and it is back to the liquid form.
This is the smallest size, and it lasts for about 30-45 minutes. There are larger sizes that will last longer.

I used to see these in pharmacies for about 4-5 dollars each all the time years ago, then didn't see them for years. My daughter has early-morning swim meets and I thought these would be good for her to keep her hands warm. They are well-made and work as advertised, but any actual useful heat lasts for maybe 20 minutes.
