Grab your ballpoint pen and write this on your calendar, June 10th of each year is National Ballpoint Pen Day. 

This special day commemorates an item that most of us use every day, the ballpoint pen and marks the anniversary of the patent filing on June 10, 1943, when Hungarian brothers Laszlo and Gyorgy Biro walked into a European patent office to declare ownership of their new writing pen design.

Their surname would go on to become generically used in colloquial British, Irish and Australian English as an alternative name for a ballpoint pen, particularly for cheaper disposable pens. Though it still remains a registered trademark.
