TWSBI Diamond 580 Fountain Pens
A Transparent Gem for the Fountain Pen Enthusiast
The TWSBI Diamond 580 series is prized for its faceted demonstrator barrel—reminiscent of a cut diamond—that shows off your ink in style. Built with a smooth piston filler and easily removable nib unit, the Diamond 580 allows both newbies and veteran pen users to explore the joy of inky tinkering. The ALR variation introduces anodised aluminium components for a subtle pop of colour. Whether you prefer a fine nib for everyday writing or a broad nib for expressive letters, the Diamond 580 offers a premium feel at an accessible price.
