MBI Matchlight

Smaller than most matches, the MBI Matchlight contains eight of the tiniest flashlights you’ve ever seen all wrapped up in a matchbook. At the bottom of each light sits a neodymium magnet that lets each flashlight stick to ferrous metals and holds them to the match case before and after use, the case itself being made of waterproof card stock and fitted with magnets as well. Each Matchlight is sealed and thus completely submersible, sports eight hours of battery life (i.e. 64 hours per matchbook of eight), and comes in one three LED colors: white, red, and green.
