This would be in local grocery or retail stores where safety matches and cigarette lighters or normally sold. I've seen them in the 1970's but can't remember how long after the '70's I've seen them. A boy at school in the 1970's struck these kinds of matches on his pants zipper to strike them during a class camping trip. The thing I hate about safety matches is often the friction surfaces on the box wear out before all the matches are used.
