TWSBI Classic Fountain Pen

The TWSBI Classic combines the brand’s reliable quality with a slim, stylish design—great for both school and work. It uses a piston-filling system, so you can fill it straight from a bottle of ink. Just twist the knob at the end to pull ink into the pen—no need for cartridges or converters. Be careful—operating the piston while ink is in the pen will cause ink to leak out of the pen.

The pen also has a clear ink window so you can see how much ink is left, and two o-rings on the end help hold the cap in place when you post it.

TWSBI believes in giving users the full fountain pen experience, so this pen is easy to take care of yourself. It comes with a wrench and some silicone grease for simple at-home maintenance.
