BIC 4 Couleurs Ballpoint Pen

The BIC 4 Couleurs (4 Colors) is an iconic retractable multi-color ballpoint pen originally introduced in 1970 by the French corporation Société Bic. Known for allowing the user to switch seamlessly between blue, black, red, and green ink, it has become a staple writing instrument across schools, universities, and offices globally.

Société Bic was founded in Clichy, France, in 1944 by Marcel Bich and Édouard Buffard. The company pioneered mass-produced, reliable disposable ballpoint pens under the BIC brand, starting with the BIC Cristal. The 4 Couleurs pen line continues to be manufactured at BIC's specialized writing instrument production facilities in France, as proudly embossed on the pen barrel ("MADE IN FRANCE").

Société Bic remains an independent, publicly traded French company listed on Euronext Paris (ticker: BB), with corporate headquarters located in Clichy, Hauts-de-Seine, France.
