Have you ever wondered why there is a hole at the end of a pen cap. Well many people say that the companies do it on purpose so that the ink dries faster and people buy more pens. Well you will be surprised to know the real reason.
It’s so that you don’t choke when you swallow it. After all, kids are known to swallow pen caps. One of the oldest and more popular ballpoints were the Bic Cristal who originally made it part of their design to include a small hole at the end of the cap. The hole is to allow passage of air in case of a dreadful event! Well at least someone is thinking for our well-being!
Stay safe!
