Fountain pens have been a source of anguish for me as they have been, I suspect, for you. I don’t know anyone who actually likes fountain pens. (That’s not true. I know a guy who collects the damn things but I always hoped it was just to get them off the street and out of the hands of gangbangers and other miscreants.)
A fountain pen, of course, is an old fashioned hybrid between a quill and a Bic. Instead of dipping your quill in a bottle of ink before splattering the ink on parchment, you’d syringe ink into a leaky bladder inside the pen before splotching it as you wrote on vellum paper. Now, of course, the ink is already inside the Bic, where it remains until it leaks into your shirt pocket.
