Ferro Buttons are low-profile, last-resort fire lighting devices. Because they replace existing buttons on your clothing, they're always with you and take up no additional space or weight. These were originally developed by Shomer-Tec for special ops military personnel for escape and evasion situations. They can also be valuable survival items for anyone who could face an unexpected survival situation in the wilderness. Ferrocerium (Ferro) is a synthetic pyrophoric alloy which produces hot sparks that can reach temperatures of 5400° F when rapidly oxidized by striking with a hard object. Size: a standard button size – 3/4" diameter, 5/32" thickness. Weight: 0.2 oz. (Ferrocerium). Color: Ferrocerium button is dark gray. Each button sold separately. Made in USA.
