TWSBI ECO Black Marble with Bronze Fountain Pen

This edition features a black marbled resin cap and piston knob, enriched with smoky grey swirls inspired by natural stone. The bronze finishes – clip, rings, and nib – add warmth and depth, creating a refined contrast with the dark marbled tones. The transparent barrel allows you to easily monitor ink level and color.

Like all TWSBI ECO, it is fully disassemblable for long-term maintenance. The box includes a wrench and silicone grease, tools intended for proper care over time rather than immediate use.
