TWSBI Obsidian Limited Edition

The TWSBI Obsidian fountain pen is a striking Limited Edition release that pairs bold styling with the reliable performance TWSBI is known for. Finished in deep black tones reminiscent of polished volcanic glass, the Obsidian offers a sleek, modern look that stands out while maintaining an elegant simplicity.

Designed with TWSBI’s trusted piston-filling system, the pen allows you to fill directly from bottled ink while providing generous ink capacity for extended writing sessions. The balanced construction and comfortable grip make it well suited for everyday writing, journaling, or collecting.

Fitted with a smooth stainless steel nib available in a variety of sizes, the Obsidian delivers consistent ink flow and a dependable writing experience.

While the pen cap will physically fit onto the back of the pen body in a way that would be considered ‘posting’, TWSBI recommends NOT doing so to avoid potentially scratching the barrel.

The Obsidian color features a new coloring technique in the injection molding process to create unique patterns and colors. Every single pen will be unique.
