Bic Cristal

The BIC Cristal (also known as the Bic pen) is an inexpensive, disposable ballpoint pen mass-produced and sold by Société Bic of Clichy, Hauts-de-Seine, France. It was introduced in December 1950 and is the best-selling pen in the world, with the 100 billionth sold in September 2006. It has become the archetypal ballpoint pen and is considered ubiquitous, to the extent that the Museum of Modern Art has made it a permanent part of its collection. Its hexagonal form and design mimics a standard pencil and it is sold in six types of point and 18 colours around the world.
