TWSBI’s ever-popular Diamond 580 ALR now comes in a Sunset Yellow anodized finish, which should complement their recent summer releases nicely. The “Sunset Yellow” model features an aluminum machined grip, connector, and piston rod. The pen has the same combination of matte finish and texture as the Diamond 580 ALR Brushed Nickel.

The TWSBI Diamond 580 is TWSBI’s classic fountain pen featuring a piston ink-filling system and swappable nib units. By fusing the traditional mechanisms of the fountain pen with a modern industrial design, TWSBI has created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present. The Diamond 580 comes with all detachable parts, as TWSBI 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 (though no disassembly is required to completely enjoy your TWSBI). Please note that the pen does not ship with ink, but ink can be purchased separately here.

The idea behind the TWSBI Diamond 580 and its predecessors, the 540 and 530, 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.
