Brass Sport Rollerball
Made from solid lead-free 'eco' brass, which is left untreated and uncoated. The untreated finish means this pen will wear over time and develop a unique patina depending on use and storage conditions.
The pen is compact when capped (approx. 4.1 inches long), but very comfortable when posted (5.2 inches long).
Refills available here.
Kaweco was established in 1883 outside Heidelberg Germany, although it was not yet called Kaweco and the design that is the most recognizable, Kaweco Sport, was not designed until 1911. A fountain pen that was not a heavy, expensive desk piece but rather lightweight and convenient was an innovation. Ballpoint pens, what we would think of as an analogy to this experience, were invented in 1888 but a reasonably functional design was not produced until 1938 and popularization came mostly after World War II, by then the Kaweco Sport was a classic as well as many other designs produced by Kaweco.
