The Grabber 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. Grabber Warmers has perfected the process so that our warmers, depending on the individual product, produce heat anywhere from 100F to 180F for a duration of 1 to 20+ hours.
