Bic’s throwaway pen was first sold with refills.
Marcel Bich launched the Cristal in 1950 as a pen you could refill, with cartridges sold separately. Buyers threw it away instead, nine times in ten by his own count in 1975, and the factory followed them. By 2005 Bic had sold 100 billion of its disposable ballpoints.
