The Kaweco Brass Sport is a fountain pen crafted from solid, lead-free eco-brass. This material choice gives the pen a substantial weight of 44g and a premium feel. The brass is left untreated, allowing it to develop a unique patina over time, which can be maintained with brass polish. Inspired by an original 1935 octagonal design, this pen is characterized by its 'Small in the pocket, large in the hand' concept. When closed, it measures 108mm, expanding to 133mm when the cap is posted. The barrel diameter is 14mm. It features a matt silver Kaweco logo on the cap end and a polished stainless-steel nib. This particular model has an Extra-Broad nib. It uses short international standard cartridges and comes supplied in a Kaweco gift tin. An optional pocket clip is available separately.
