In the 1960s, the fiber- or felt-tipped pen was invented by Yukio Horie of the Tokyo Stationery Company, Japan.[21] Paper Mate's Flair was among the first felt-tip pens to hit the U.S. market in the 1960s, and it has been the leader ever since. Marker pens and highlighters, both similar to felt pens, have become popular in recent times.
