TWSBI Precision Gemini Blue Fountain Pen
A striking addition to TWSBI's Precision lineup. This edition features a bold matte metallic blue finish, perfectly complemented by sleek silver accents for a clean, modern aesthetic.
Built with the same rugged, industrial design the Precision is known for, the Gemini Blue offers a solid, well-balanced feel in hand and a smooth writing experience. Its piston-filling mechanism allows for a generous ink capacity, while the clear ink window lets you keep an eye on your ink level at all times.
Whether you're a longtime TWSBI fan or new to the brand, the Precision Gemini Blue is a vibrant, reliable workhorse that blends form and function beautifully — perfect for everyday writing with a pop of color.

TWSBI Diamond Mini Clear
TWSBI Diamond Mini Clear Fountain Pen. Transparent crystal-clear diamond-faceted barrel reveals the filling mechanism, a built-in piston-filler with a very smooth action, while also allowing an uninterrupted view of the ink level and color. TWSBI logo nicely finishes the top of the pen's cap. Rubber O-ring on cap thread ensures an airtight seal to prevent ink drying out in the pen, while also ensuring that the cap is firmly attached when not in use.
