TWSBI Emerald Green Diamond 580AL Fountain Pen

This TWSBI Diamond 580AL fountain pen blends modern industrial design with traditional mechanical craftsmanship. The signature diamond-faceted clear polycarbonate barrel reveals the inner workings of the pen, elegantly showcasing a bright emerald green aluminum grip section, connector, and piston rod assembly.

The cap and end accents feature matching polished emerald green finishes and chrome trim, complete with a secure screw-on cap design. Engineered with a benchmark internal piston ink-filling mechanism, the pen draws fountain pen ink directly from the bottle into the cavernous reservoir barrel without needing a separate cartridge or converter.

Preserved in pristine condition, the transparent demonstrator window remains perfectly clear and free from any clouding, ink staining, or usage scuffs. Housed inside its original retail storage case, this striking writing instrument is a standout collector's item for fine stationery enthusiasts and everyday writers alike. This is a Limited Edition 2019 release, highly collectable.
