These reusable hand warmers come in Donutella & Unicorno shapes and are perfect to keep you warm on-the-go.
The magic of these hand warmers is in the round metal disc you see inside it. All you need to do is to firmly press the disc and you will see the clear gel inside become opaque white. This cool chemical reaction starts an exothermic crystallization of the gel, as the opaqueness spreads, so does the heat!
Once it has cooled down and hardened, cover it with a cloth for protection and submerge in a pan of cold water. Bring to the boil and simmer for around 5 minutes until the gel becomes clear again. Allow the water to cool before removing the hand warmers. Once it cools off from its boiling bath, it is ready to be used again. A great and fun way to keep your hands warm during the winter! Do not place in microwave.
