Namiki (Vanishing Point) Fountain Pen

(Made by Pilot)

Beautiful to look at, smooth writing, and very cleverly designed. It never leaks, not even on airplanes. Note that it is a retractable point -- the only such fountain pen. Also note the design features. When closed and put into a pocket, the point is upwards, reducing the chance of leaking. There is a tiny door (invisible, because it is inside the pen, just below the mouth) that shuts when the pen is retracted, preventing the tip from drying out. And the clip both prevents the round pen from rolling when placed on a flat surface and also guides the fingers to hold the pen in the correct writing position when the pen is in use. Namiki website.
