Prussian Blue is a Limited Edition color.
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. By fusing the traditional mechanisms of the fountain pen with 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 a benchmark ink-filling mechanism and has all detachable parts. TWSBI feels 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.
The crystal clear body allows for an unobstructed view of the ink level in the barrel, which holds almost 2ml of ink.
The clear cap is threaded and posts on the piston knob (we recommend using it un-posted), and features a silver clip. An inner cap also provides a seal when the pen is stored for longer periods of time.
The 580 is refilled by turning the piston knob counter-clockwise until the piston is at the front of the barrel, and then submerging the nib section in ink and turning it again clockwise to draw the ink into the barrel. There are no cartridges or converters!
TWSBI also includes in the box a tool to disassemble the pen and silicone grease for regular maintenance.
Note: Ink is not included with this pen.
