TWSBI Diamond 580 RBT

Fountain pen.

The new TWSBI Diamond 580 RBT, a classic fountain pen with a piston ink-filling system and 1.9cc ink capacity.

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.

Comes with a smart, modern clear box and a little vial of silicone grease to lubricate the piston over time.
