Abstract: An organic plastic matchbook cover having continuous front, back and side walls, and that is closed at its bottom and generally open at its top. The walls and bottom define a generally wedge-shaped interior cavity having the size and shape necessary to receive a conventional paper matchbook therewithin. An opening is provided in the front wall of the cover in position to overlie the striking surface of the matchbook, and a second opening is provided in the back wall to permit a thumb or finger to engage the back of the matchbook. A holding tab projects from the top of the back wall partially across the top of the cover towards the front wall in position to overlie and engage the top of a matchbook positioned in the cavity, and a locking tab projects inwardly from each of the side walls.
