As the most popular pen in the world, Bic Cristal pens have sold over 100 billion units in the past 60 years (The Guardian, 2005). They are available in nearly every country in the world at a range of stores and retailers. Socially, this simple product helps create an maintain a great deal of jobs if only in a small way. On the other hand, the consumption of so many pens means that more are produced, meaning more natural resources used and more exhaust generated in transporting them. This poses a difficult problem.
