TWSBI ECO Cosmo w/Onyx Fountain PenTWSBI fountain pens are beloved for their clear barrels (sometimes called demonstrators) that allow users to see the ink inside. The pen has an interior ink filling piston system that holds much more ink than a typical fountain pen cartridge. It also allows you to fill your pen up with ink without the use of a converter. Just unscrew the cap at the end of the pen, dip the pen into ink, fill, and screw the cap back on. The TWSBI ECO (for "Economical")
