The Kaweco BRASS Sport is the heavyweight of the Sport series, and is turned from first-class brass. Weighing 44g, this ballpen is the heaviest Kaweco ballpen. The cap and barrel are manufactured in two complex processes to create this stunning piece of German engineering. Brass has been valued since ancient times for its beauty and durability. The Eco brass fountain pen contains no lead in the formula of the brass, so the pen will age more like copper than regular brass. Slight colour variations occur naturally, the appearance of each Liliput pen may vary from the photos, and the colour may not be uniform throughout the pen. Over time, the colour will deepen as the brass oxidises, creating a natural patina. Preview Html
