TWSBI Diamond 580 Fountain Pen IRIS

TWSBI Diamond 580 Fountain Pen IRIS

The TWSBI Diamond  580 Fountain Pen IRIS is a new fountain pen made by the taiwanese pen company TWSBI.
By fusing the traditional mechanisms of the fountain pen with a modern industrial design, TWSBI have created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present!
The TWSBI Diamond  580 Fountain Pen IRIS 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 grip section, the head logo and the ring on the cap of the new TWSBI Diamond  580 Fountain Pen IRIS,  are all made of metal with a "IRIS" colour.
