You’ve seen it before when using a black or blue ballpoint pen. The little hole in the top of the pen cap. But why?
It’s actually for a very good reason that could save lives! The purpose of the hole is so in the event that someone accidently swallows the pen cap air can still flow through and the person won’t choke or lose their breathing. This can happen to anyone kids or adults. It can be avoided by not chewing on your pens which is a bad habit for a lot of people. But if it does happen, now you know what that little hole is for.
Thank you pen companies, for looking out for our safety,
