A permanent match, also known as a Forever Match, is a reusable match that typically includes a metal body, a metal match with a wick on top, a built-in lighter fluid reservoir, an O-ring seal for the reservoir to keep the fluid from evaporating (it also helps make the match waterproof), a striking surface, and a ferro rod, flint, or magnesium core to provide the fire-starting spark. The best permanent match like the Everstryke Match will provide thousands of reliable strikes even under the most adverse weather conditions.
