TWSBI Diamond 580 Fountain Pen - Iris

£75.00 GBP

Nib Width

The new and improved TWSBI Diamond 580. The new 580 model is an improved version of the Diamond 540, with a piston fill mechanism and 1.9cc ink capacity. Also, available as a Clear Demonstrator, with a choice of nib widths.

Comes with a smart, modern clear box and a little vial of silicone grease to lubricate the piston over time. There is an instruction sheet and small spanner to take the piston mechanism from the barrel to allow the lubricating.

The nib, ink feed and grip section can also be taken apart for cleaning and maintenance - it is not advised unless necessary, but it can be done. Best advice is to enjoy the great design, writing experience and value!
