The permanent match is a neat (and very effective) little fire starting tool. The "match" portion is a metal rod with a wick inside and a scraper on the end. When it is soaked with lighter fluid from inside the reservoir, the match is struck against the attached firesteel to light the wick and give you a long burning flame. When the match is not in use, it threads into the reservoir and stays tightly sealed with the attached o-ring to keep the fluid ready for the next time you need the tool. The durable body is constructed from stainless steel and ABS plastic and is approximately 2.3" x .8".
