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 modernization 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.

The body of the pen is made up of plastic. The nib is of stainless steel. Screwed type mechanism. This pen has all the detachable parts. The ink capacity is higher. Piston ink filling system [note: ink is not included]. The body of the pen is transparent so you can easily check the ink level.

The use of the ink cartridge and converter is not possible. The pen comes with an instruction manual, silicone grease, and wrench. The pen comes in a paper(outer) box and plastic(inner) box.
