If you’re like me, you’ve never really understood why there is that hole at the end of a pen lid. Well, wonder no more, because the answer is here!
It turns out Bic knew that a common habit was to chew on a pen lid while working, and that at some point it could get a bit further than your teeth.
So, Bic introduced a tiny hole in the lid to reduce suffocation should the lid end up somewhere between your mouth and your stomach.
Interesting stuff for a Friday morning, right?
