More info

The enhanced version of the TWSBI Diamond 580 AL features lovely sunset yellow anodised aluminium piston parts and a matching grip section with a gently ribbed texture. The TWSBI Diamond 580 ALRSunset Yellow 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.

Excellent pen but some issues

Wonderful service from The Writing Desk. There is not much I can say or add to this well established and regarded pen. My Sunset Yellow 580 ALR with M nib looks and writes beautifully out of the box.
The quality and value of the pen is overall excellent. However perhaps my pen has some unexpected small issues with the piston filling mechanism. The knob piston mechanism has really too much, excessive "play". In addition the piston filler knob on my pen requires excessive tightening to remain closed. A normal or expected twist to lock the knob results in it easily becoming loose in handling. Having owned many Twsbi pens this was unexpected.
