Our mini hand warmers, toe warmers and ultra warmers contain natural ingredients that produce heat when exposed to air; this is accomplished via a rapid oxidation process. Ingredients include iron powder, water, salt, activated charcoal and vermiculite. The warmers, depending on the specific product, produce heat for a duration of 5 to more than 20 hours.
These warmers are made of natural ingredients and are safe for the environment; you can simply use and dispose of them in your everyday garbage. Each warmer’s temperature, heating duration and shape is designed to provide the best customer experience based on where the warmer is used. Although all warmers are safe to handle and use, some people with sensitive skin (especially young children and the elderly) may have reduced sensation to heat, which is why we recommend against applying the warmers directly to skin. The body warmers are designed for one-time use and there are no restrictions with taking them aboard or using them during flight – they are completely safe for air travel.
