For more than half a century, TWSBI have been crafting pens for renowned global brands, an experience that inspired them to launch their own brand. As experts in the field of pens, their mission revolves around creating the highest quality pens while maintaining affordability.

The TWSBI Diamond 580 is a timeless fountain pen, boasting a piston ink-filling system, so that you get maximum ink capacity inside your pen. Combining classic mechanics with a contemporary aesthetic, this piece is both a nod to the past and an embodiment of modernity with its rose gold accents and opaque white finish. The Diamond 580 is designed with full functionality, with all detachable parts to enable you to completely disassemble the pen. The barrel of the pen is clear, so you can see the clever inner workings of the pen, as well as easily see your current ink level and colour.
