Our HotHands® family of air activated warmers all contain a mixture of natural ingredients that when exposed to air react together to produce heat. This is accomplished through an extremely fast oxidation process. Ingredients include: iron powder, water, salt, activated charcoal and vermiculite. HotHands® has perfected the process so that our warmers, depending on the individual product, produce heat anywhere from 100°F to 180°F for duration of 1 to 20+ hours.

HotHands® warmers are made of natural ingredients and safe for the environment. Just use and dispose of in your everyday garbage.

Because of this, please read product instructions on each package for additional features and important product information.
