Nevercold Handwarmer

Nevercold Hand warmers are handy extra warmth bags that you can use to warm your hands or keep, for example, phone or device batteries warm on cold, frosty days in winter.

Nevercold Hand warmers are small pillow-like bags made of porous material, with a mixture of vermiculite, iron powder, wood powder, activated carbon and salt inside. When the sales package surrounding the bag is opened, the mixture can react with the air, causing heat to form. The reaction continues on its own for 10 hours. The production of heat can be stopped by moving the bag to an oxygen-free place, e.g. into an airtight minigrip bag, so you can continue using the heater later.
