TWSBI Precision Fountain Pen – Gemini Blue (Special Edition)

Engineered for performance and styled for distinction, the TWSBI Precision Fountain Pen in Gemini Blue is a sleek, limited-edition writing instrument crafted from solid aluminum in a striking deep blue finish. Paired with stainless steel trim and a matching steel nib, this pen is both bold and refined—designed for those who appreciate form and function in equal measure.

Equipped with TWSBI’s signature piston-filling system, the Precision allows for a generous ink capacity and smooth writing experience. Like all TWSBI models, it’s designed to be fully disassembled and maintained by the user, giving fountain pen enthusiasts a deeper connection to the traditional mechanics of writing. The pen includes a wrench and silicone grease for long-term maintenance—no need to use them right away, but they’re there when you need them.

Please note: while the nib is the same as the one found in the TWSBI Diamond 580, the entire nib unit is not interchangeable. Only the nib itself can be swapped.
