The TWSBI ECO Piston Filler Fountain Pen – Smoke Rose Gold is the most elegant model in the ECO lineup, offering a luxurious twist on the classic demonstrator. It features a deep, rich "Smoke" dark grey finish on the cap and piston knob, which appears nearly black in most lighting, providing a stunning contrast to the Rose Gold plated trim.
The ECO (short for "Economical") is famous for bringing high-end piston filling mechanisms to an accessible price point. The built-in piston allows you to fill the pen directly from a bottle, holding a massive 1.76ml of ink. The crystal-clear barrel allows you to monitor your ink level while the warm rose gold accents add a professional, jewelry-like quality.
Designed for daily use, the cap features an inner seal to prevent the nib from drying out, even if left unused for weeks. The distinct hexagonal cap prevents the pen from rolling off your desk, while the round grip section ensures a comfortable writing experience.
True to TWSBI’s philosophy of user empowerment, the pen arrives in a presentation box that includes a wrench and silicone grease, allowing you to fully disassemble and lubricate the mechanism yourself—ensuring your pen lasts a lifetime.
