Somehow not a problem I have - still have my original 2018 iPad stylus, and I don't lose regular pens either.

Suspect this is a mindset thing if you mostly use 10 cent Bic pens you'll never care to make a habit of keeping them, and then when you're using an expensive gadget pen those habits carry over.

Even a pen that costs a few bucks (Signo UM-151 for instance) I know where they're at.
