Clear Demonstrator Fountain Pen with Piston Filling and a Stainless Steel Nib for Traditional Writing
This clear demonstrator fountain pen puts your ink color and remaining ink level in view, so you can check the barrel as you write. The TWSBI Diamond 580 pairs a piston ink-filling system with a stainless steel nib, bringing traditional fountain pen mechanics into a modern industrial design.
A clear grip section continues the transparent look, while a screw-cap closes the pen between writing sessions. The pen comes in a clear display case and includes a wrench and silicone grease for long-term care. Its detachable construction allows disassembly and reassembly; handle the nib and feed carefully because the feed is fragile.
