The Kaweco Lunar Sport Fountain Pen in Shadow Green offers a striking iridescent pearl‑effect finish that shifts from deep green to shimmering bronze under light. Compact at 105 mm closed and 130 mm posted, it features an iconic octagonal cap and a smooth round barrel for a comfortable grip. Made from high‑quality ABS plastic, the pen weighs just 10.5 g, making it ideal for long writing sessions. A unique 060 exchangeable nib section lets users screw in different nib sizes (EF to BB) without tools, while a standard Royal Blue ink cartridge is included. The pen comes in a standard Kaweco paper gift box and is perfect for beginners and collectors alike.
