Hello Kitty, Cinnamoroll and Kuromi instant cold packs. I bought them at dollar store Daiso. The package said that it keeps cold about 15 min, so I verified the effects. The mechanism of instant cold pack is endothermic reaction of urea and water. It's simple and fun. But it isn't good to touch urea directly, so don't open instant cold packs.
