Fire

A matchbook is a different way to store matches than the more common matchbox. Matchbooks are essentially a folded over piece of cardboard with a rough strip on the outside for striking the matches on. The matches in the matchbook are all attached together in a row, and also attached to the inside of the matchbook. They are also made from cardboard, and must be torn off before they can be used.

A match is a small stick with chemicals at one end that catch fire if they are rubbed along a rough surface. Matches are usually sold in a matchbox or matchbook that has a rough edge on one side to strike your matches on.
