TWSBI ECO Special Edition History - The Goulet Pen Company

A visual look back at all of the new TWSBI ECO (and ECO-T!) fountain pens, including special and regular editions that have been available in the United States.

The TWSBI ECO fountain pen is one of our best selling fountain pen models and for good reason -- fans love its modern design, large ink capacity with the built-in piston filling mechanism, reliable steel nibs, and affordable price. The frequent release of new colors makes it a popular collector's item.
