New Fountain Pens

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.

Inspired by the timeless beauty of lapis lazuli, the M200 Golden Lapis captures the essence of a gemstone long associated with wisdom, strength, and inner balance.

Its rich blue body is accented with a captivating golden shimmer, creating a luminous, ever-changing appearance. The velvet-matte, semi-transparent material subtly reveals the inner piston mechanism—adding depth and visual intrigue to the design.

Pair it with a shimmering ink and gently agitate before filling to enjoy dynamic variations in color and sparkle with every stroke. A striking blend of elegance and functionality, the Golden Lapis offers both a unique aesthetic and a rewarding writing experience.

All black. All bold. Pure presence.

The M809 Black Matte is a striking expression of modern design, finished entirely in deep, understated black—from the barrel and cap to the trim and 18k gold nib. A refined contrast of textures pairs satin-finished metal with high-gloss precious resin, creating a sleek, monochromatic silhouette with subtle visual depth.

A discreet smoked ink window blends seamlessly into the barrel, maintaining the pen’s clean, uninterrupted look while offering just a hint of transparency.

Beyond its appearance, the M809 Black Matte delivers a premium tactile experience. The soft matte surface provides a comfortable, lightly grippy feel, ensuring stability and control in hand. Thoughtfully crafted and unmistakably distinctive, this is a pen that stands out through both form and function.
