Enhanced version of the TWSBI Diamond 580 AL that features dark blue anodised aluminium piston parts and matching grip section with gently ribbed texture. The TWSBI Diamond 580 ALR Prussian Blue features the same piston filling mechanism as the standard Diamond 580 AL and a huge 1.9cc ink capacity - the largest of any pen in this price range.
Five nib options are available for this pen, from extra-fine (EF) to broad (B) plus a 1.1mm italic style nib. You can easily change nibs too as they unscrew from the front of the barrel.
The Diamond 580 models are virtually unique amongst fountain pens in that they can be completely disassembled by the user for cleaning and servicing and experienced users are encouraged to do so. Full servicing instructions are included with the pen as well as a small wrench to remove the piston mechanism and a bottle of silicone lubricant for the piston mechanism.
Piston-filling mechanism (uses bottled ink only). As this pen only uses bottled ink, check out our huge collection of fountain pen inks.
See our reference section for more details on TWSBI nibs.
