TWSBI Diamond 580 Fountain Pen

TWSBI Diamond 580, a classic fountain pen with a piston ink-filling system. By fusing the traditional mechanisms of the fountain pen with a modern industrial design, we have created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present. The Diamond 580 comes with a benchmark ink-filling mechanism and has all detachable parts. We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.

The TWSBI 580AL fountain pen builds upon the 580, but there are basically 4 parts of the pen that are aluminum instead of plastic: the grip, the screw, the connector, and the screw bolt.

The TWSBI 580ALR also features the same aluminum parts. The difference being that the grip itself is engraved with subtle rings around the circumference of the grip and cap.
