Ballpens have been around for a long time, and used by many people because of its reliability and affordability.
But there’s one feature of a pen that could save someone’s life.
A brand “Bic” saw a habit of peoples especially children on how they use their ballpen. Users sometimes chew on the cap and the company feared that it may be inhaled and could stuck on someone’s throat.
That’s why the company put holes on their caps, so if an accidental inhalation happens the patient still can breathe and can be further treated properly.
