What is a Ballpoint Pen?
A ballpoint pen is a type of writing implement invented in 1938 by Laszlo Biro. The ballpoint pen represented a significant improvement over fountain pens, which had a tendency to leak and could also fail at high altitudes. Biro’s invention was widely used throughout the Second World War, and has come to be a common product in most households around the world, thanks to cheap manufacturing processes which make ballpoint pens readily affordable.
