TWSBI Special Edition Piston Fountain Pen

TWSBI Obsidian

The Special Edition by Taiwanese brand TWSBI is a masterpiece that balances natural aesthetics with precision engineering, designed for those who appreciate the subtle beauty of mineral textures.

Featuring a built-in piston filling mechanism, it offers a generous ink capacity, ensuring a reliable and seamless writing experience. The nib is crafted from high-quality stainless steel, delivering the smooth and stable performance that TWSBI is renowned for.

Obsidian (Onyx): Inspired by the mysterious allure of natural volcanic glass and deep-earth minerals. Unlike a standard solid black finish, the Obsidian edition features a captivating blend of black and deep charcoal swirls, mimicking the organic veining of genuine onyx or obsidian stone.

The marbled effect creates a sophisticated depth; as the light catches the pen from different angles, hidden layers of dark, interlaced textures are revealed. It is a design that feels alive—a modern writing instrument that carries the timeless, grounding essence of natural stone.
