About the TWSBI ECO Piston Filler Fountain Pen – Espresso Bronze

The TWSBI ECO Piston Filler Fountain Pen – Espresso Bronze is a warm, sophisticated Special Edition that pairs the rich tones of roasted coffee with the vintage appeal of bronze. This model features a deep Espresso Brown cap and piston knob, beautifully accented by Bronze-plated trim and a matching bronze-plated nib.

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 not only lets you monitor your ink level but turns your ink choice into a visual part of the pen's aesthetic.

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.
