TWSBI ECO Cerulean Fountain Pen — Extra Fine
£36.00
The TWSBI ECO is the brand’s entry-point fountain pen: a piston-filling demonstrator that brings the working principles of a much more expensive pen down to a more affordable price.
This Cerulean edition has a clear blue barrel and matching cap with the ECO’s faceted screw mechanism, the same robust design that’s made it TWSBI’s runaway bestseller. The piston holds a healthy ink capacity and the steel nib writes wet and reliably.

TWSBI was launched in 2009 in Taiwan by Ta Shin Precision, a manufacturer with decades of experience producing plastic and metal components for other companies before turning that expertise to fountain pens of its own. The name comes from the Chinese phrase "San Wen Tong" — the Hall of Three Cultures — with the initials reversed to form "TWS" and "BI" added for its meaning of writing instrument.
The brand is best known for its piston-filling demonstrator pens, including the Diamond 580 and the hugely popular ECO. Clear barrels show off the ink and filling mechanism, while a level of build quality usually reserved for far more expensive pens is offered at a genuinely accessible price.
