TWSBI Diamond 580 Iris Fountain Pen

The Diamond 580 is TWSBI's flagship demonstrator pen, and the Iris finish brings a deep, jewel-toned purple to its faceted acrylic body — a design that lets you see the piston mechanism in action every time you write.

Key Features

  • Faceted "diamond-cut" acrylic barrel in a rich Iris purple
  • Stainless steel nib, available in Extra Fine, Fine, Medium, Broad, and Stub 1.1mm
  • Fully transparent design showcasing the internal piston mechanism
  • Fully detachable parts for easy cleaning and maintenance

Filling System

The 580 uses a piston-filling mechanism with roughly 30% more ink capacity than TWSBI's earlier 530 model, along with a smoother-turning cap thread for everyday reliability.
