TWSBI Diamond 580 AL R Prussian Blue fountain pen with a piston ink-filling system.
The pen has a diamond-faceted, metal trim and pocket clip. Now with matte finish, subtile details on the grip and cap.
The cap is smooth while the barrel is faceted. The transparent barrel reveals the piston filling mechanism.
The gripping section, connector and screw of the pen are all made of metal with a blue color.
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.
