Good to know
In 1984, the first gel pens were produced by a Japanese corporation in Osaka, Japan, called Sakura Color Products. Their first product which became available in America in the late 1980s was the “Gelly Roll”. Following this, Crayola jumped on the gel pen band wagon, producing pens with thicker bodies, marketing them to children. The gel of these pens were made up of metallic sparkles and fluorescent colours, popular among artists for their easy control and smooth drawing capability.
