The Science Behind Pen Cap Holes

If you have ever wondered why some companies design pen caps with holes in them, it’s your lucky day because we have some facts to answer these questions. First, we are sure that most families have at least one kid or adult who has swallowed the cap sometime in their life. Mistakenly, of course.
When this happens, these holes allow the free flow of air through them, which reduces incidents of choking that could lead to something much worse. So that’s the big picture behind a design that looks random but serves a purpose and saves lives!
