Heat Factory Foot Warmer Designed for use in Heat Factory Footbeds and products only. Specially designed Footwarmer that works in restricted and confined spaces. Up to 6 hours of continuous heat.
Heat Factory Footwarmers are designed to go with the Heat Factory foot beds or/and heated socks. You get heat that will last up to 5 hours. Unopened, the Heat Factory warmers have a shelf life up to three years. If the heating time has not been completely used the process may be stopped by putting the Heat Factory warmers in an air tight container. Later they can be open again and the remaining heating time of the warmer may be used.
The heat packs are a soft light weight pouch containing a mixture of iron powder, charcoal, salt, sawdust and vermiculite that reacts to the air. When you open the package, an oxidation process takes place and heat up. Simple to use and they work!
