The TWSBI Classic fountain pen has a slim and sophisticated body with a high capacity piston filling mechanism featuring an ink window. 
We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.

Additional Description

The classic look, with piston filler functionality.
