I own a Pilot birdie which is extremely small but beautiful fountain pen. It resembles a tiny stainless steel rod. It was part of the "Birdie" collection which came also with a ball pen and mechanical pencil. Unfortunately as all good things they don't seem to manufacture them anymore. I started using it some time ago because I'm tired to buy plastic pens, also the its stroke is much better than anything else I've used so far. Fountain pens are a world.
