TWSBI Diamond 580 ALR Fountain Pen

The idea behind the TWSBI Diamond 530, 540, and 580 was to go back to basics and capture the simplicity and elegance of traditional writing instruments. In recent years, the development and modernisation of writing instruments has resulted in traditional writing instruments, such as fountain pens, falling into obscurity. It was our goal to bring the past back to life by creating a traditional fountain pen that even modern day society can appreciate.

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.

Our ever popular 580AL now with matte finish, subtile details on the grip and cap. 
New aluminum machined grip, connector, and piston rod.
