That little hole on your pen cap isn’t there by chance: here’s what it’s really for.

Some brands have gone even further. BIC, for example, has made this hole a true identifying feature. It is now part of the product’s aesthetic, instantly recognizable.

This proves that a purely technical detail can, over time, become a visual signature. A bit like those little everyday things that end up defining a cult object.

What if all caps have this hole? Not quite — some models still don’t. But major brands adhere to this standard, and that’s a good thing.

The next time you pick up your favorite pen, you’ll look at that little hole with completely different eyes.
