Bic Cristal
You can read its useful details at a glance: a transparent barrel shows the ink level, the cap signals the colour, and the hexagonal body resists rolling off a desk. The Cristal makes an everyday writing tool legible without instructions or decoration. Its appeal here is economical design: several small annoyances solved with very few parts.

About Bic Cristal
The Bic Cristal (stylised as BiC Cristal and also known as the Bic Biro) is an inexpensive, disposable ballpoint pen mass-produced and sold by Société Bic of Clichy, Hauts-de-Seine, France. It was introduced in 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 colors around the world.
