I have no affiliation with jetpens - but if you are into pens at all, buy one of their sampler packs. It's a great way to try out different styles of pens that you won't find at Staples or Walgreens (or the office supply closet).
pens that you won't find at Staples or Walgreens (or the office supply closet) You'll still have to hit up the office supply closet or one of those other places for "decoy pens." You leave the decoy pens in a cup on top of your desk, while you keep the good stuff inside a drawer. That way your officemates and/or partner and/or housemates borrow (steal) the decoy pens and not the good stuff.
It goes back to when someone in the MIT student center asked to borrow a pen to fill out an ATM deposit slip, I had only a Cross pen engraved with my name and the first project team I was on, and I reluctantly handed it over while emphasizing that I needed it back...
