How Do They Work?

The heat produced by our Hand Warmers is caused by a natural chemical reaction. The Hand Warmers begin to work when exposed to air as each ingredient performs a special function.
  • Iron and Oxygen react together to produce heat - a "rusting" process.

  • Salt is a catalyst speeding up the heat reaction.

  • Activated carbon acts like charcoal in your BBQ and disperses the heat around the Hand Warmer.

  • Vermiculite insulates the reaction in the Hand Warmer so it lasts longer.

  • Air sealed packet keeps the moisture within the Hand Warmer.
