Mini hand heaters, toe warmers and ultra warmers - contain natural ingredients that when exposed to air react together to produce heat. This is accomplished through a rapid oxidation process. Ingredients include: iron powder, water, salt, activated charcoal and vermiculite. Warmers, depending on the individual product, produce heat anywhere for duaration of 5 to 20+ hours.
These warmers are made of natural ingredients and are safe for the environment. Just use and dispose of in your everyday garbage. Each warmer’s temperature, duration and shape are 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, that’s why the warmers can’t be applied to skin directly. 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.
