The fountain pen 580 AL comes with a benchmark piston ink-filling mechanism and has all detachable parts. The clear demonstrator barrel allows you to see your ink color and remaining ink level. It has a silver aluminum grip section and a screw-cap. It comes with a stainless steel nib and is presented in a modern clear display case.

The idea behind the TWSBI Diamond 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 have 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.

The TWSBI Diamond 580 is 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 has created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present.

TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories is intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile. You may notice a white substance on your 580AL or 580AL R pistons. This is bearing grease, and must not be removed during cleanings, or replaced by silicone grease.
