Ever wonder why there is a hole at the top of ever pen lid?
I always assumed it was to stop it from suctioning on and sticking – but i was wrong.
Ever chew on your pen lid, turns out the hole is just in case you swallow it, so it doesn’t block your airway.
From the Bic website:
“In addition to help prevent the pen from leaking, all our BIC® caps comply with international safety standards that attempt to minimize the risk of children accidentally inhaling pen caps. Some of these vented caps, like that used for the BIC® Cristal®, has a little hole in the top to comply with the existing safety standards.”
