TWSBI Diamond 580 AL R Fountain Pen - Prussian Blue
The TWSBI Diamond 580 AL R Prussian Blue is a premium piston-filling fountain pen that combines a bold, deep blue aluminium body with TWSBI's renowned engineering precision — a step up from the Eco for writers who want more heft and refinement.
The 'AL R' designation means the grip section, connector and piston rod are all machined from aluminium, giving the pen a satisfying weight and exceptional durability. The result is a pen that feels substantial in the hand without being heavy.
Key specifications:
- Filling system: Piston
- Body material: Aluminium grip & trim, resin barrel
- Length capped: 14.2cm | Posted: 17.5cm
- Nib options: EF, F, M, B, 1.1mm Stub
Each pen comes presented in a clear gift box and includes a vial of silicone grease, an instruction sheet, and a small spanner for piston maintenance — everything you need to keep it writing perfectly for years.
The nib, ink feed and grip section are fully disassemblable for deep cleaning. The piston mechanism can also be removed for lubrication when needed.
