TWSBI Diamond 580 Fountain Pen – Clear
The original Diamond 580 demonstrator, in fully clear resin — a great way to see exactly how TWSBI's piston filling mechanism works. 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, letting you disassemble and reassemble the pen and experience the traditional aspects of owning a fountain pen.
The diamond-cut barrel catches the light beautifully and keeps the pen from rolling off a desk, while a stainless steel nib is available in five sizes.
