The Twsbi Precision Gemini Blue fountain pen combines the value of Twsbi with stylish, modern pen design. The hexagonal aluminum pen body prevents rolling and adds a modern touch to this high-quality fountain pen design. The brushed aluminum finish and angled clip create a sleek and stylish look.
The Twsbi Precision fountain pen features a high capacity piston filling system, activated by twisting the piston knob at the end of the barrel. By turning the knob counter clockwise, the piston extends, while a clockwise twist retracts the piston for refilling directly from an ink bottle.
The transparent ink window in the grip section, visible upon removing the threaded cap, allows for easy monitoring of ink levels.
The piston knob also includes two o-rings for a secure post, providing convenience for those who prefer to write with the cap posted.
Each pen comes with a wrench and vial of silicone grease for at-home maintenance.
