The TWSBI Diamond 580 shows the company’s commitment to continuous product improvement. The Diamond 580 boasts a 30% increase in ink capacity over the original Diamond 530.

The idea behind the TWSBI Diamond 580, along with the 530 and 540 before it, was to go back to basics and capture the simplicity and elegance of traditional writing instruments. In recent years, the development and modernization of writing instruments has resulted in traditional writing instruments, such as fountain pens, falling into obscurity. It was TWSBI’s 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, TWSBI 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 piston ink-filling mechanism and has all detachable parts. TWSBI felt that it was important to allow the user to be able to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.
