About the TWSBI ECO Piston Filler Fountain Pen – Caffe Bronze

The TWSBI ECO Piston Filler Fountain Pen – Caffe Bronze is a warm, inviting Special Edition that evokes the comfort of a morning latte. This model features a soft, creamy coffee-brown cap and piston knob, elegantly offset by warm 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.
