TWSBI Diamond 580 Fountain Pen – Iris
The Diamond 580 is TWSBI's flagship demonstrator pen, and the Iris finish brings a deep, jewel-toned purple to the clear body, with rainbow-colored iridescent trim and a stainless steel nib accented with iridescent color. By fusing traditional fountain pen mechanisms with a modern, faceted industrial design, the Diamond 580 comes with a benchmark piston ink-filling mechanism and has all detachable parts.
The diamond-cut barrel catches the light beautifully and keeps the pen from rolling off a desk, while the stainless steel nib is available in five sizes.
