THE HEAT company(r) warmers are non-toxic and can be disposed of in normal household waste.
The Austrian Police Force and Army have been using these warmers for years.
Also athletes of the German Ski Federation (DSV), the "Swiss Ski" National skiing team of Switzerland and the AUSTRIAN SKI TEAM around Hermann Maier are using HEAT toewarmers.
Our hand, foot and body warmers are made from 100% natural, non-toxic materials:
1) Vermiculite is a soft mineral which influences the ground fertility due to its high tendency to exchange ions.
Vermiculite is similar to mica minerals and it forms flaky crystals.
This mineral is often used in cat litter and ground fertilisers.
It can also be found in buildings as a safe alternative to asbestos for sound and heat isolation as well as fire protection.
2) Charcoal (active carbon) is a fine grain carbon (90% carbon materials) with a large surface area and a highly porous structure.
The pores are similar to a sponge in that they are bound together on top of one another.
To give you an idea of the porous structure of this material the inner surface area of 2 grams of this charcoal has a surface area of a football field.
