The Classic Sapphire is an affordably priced, well performing fountain pen with a high capacity piston filling mechanism. TWSBI has quickly grown in popularity within the past few years with consistently stellar reviews from the fountain pen community.
The piston is used to draw ink by twisting a knob at the end of the barrel. Unique to the Classic model is a small ink window above the grip. With chrome appointments and a threaded twist cap, the TWSBI Classic fountain pen is both sharp and reliable.
This unit is compatible with all bottled fountain pen ink and includes a pen wrench with silicone grease for care and maintenance.
