The TWSBI ECO (short for “economical”) provides the same high-quality, high-capacity piston filler as the TWSBI Diamond 580 at an even lower price. It features a sleek, transparent barrel and a hexagonal screw-on cap that can be posted securely on the back of the pen.
ECO-T has a slightly more pronounced grip section; to help with learning correct writing posture for kids, new enthusiast, and anyone who likes a little bit more structure to the grip area. Cap and end cap also has a rotary triangular shape design.
The pen comes in an attractive clear plastic case with a clean, modern design. For protection, the plastic case is packaged in a cardboard box.
Note: This pen only uses bottled ink, which is not included with this pen.
In keeping with their philosophy of promoting the traditional experience of using a fountain pen, TWSBI has designed this pen to be completely self-serviceable. It comes with a wrench and a vial of silicone grease you can use for at-home maintenance.
