TWSBI ECO Slate Blue with Onyx Fountain Pen

TWSBI ECO fountain pen delivers outstanding quality with a smooth piston-filling mechanism, all at an affordable price. Featuring a striking hexagonal cap and piston twist tip in a refined slate blue, complemented by sleek onyx black trims, this pen exudes a modern and sophisticated style. The transparent demonstrator barrel allows you to view the ink level and piston mechanism in action, while the gently tapered grip section ensures a comfortable writing experience. A rubber O-ring between the barrel and twist-off cap creates a secure seal, preventing leaks and ink from drying out.

As with all TWSBI fountain pens, the ECO can be fully disassembled for cleaning and maintenance. While tools are included, TWSBI advises that only experienced users attempt disassembly, and it should only be done as part of long-term maintenance. Any disassembly is undertaken at the owner’s risk.
