The Kaweco AL Sport ballpoint shown here in Raw Polished is compact yet functional, thus supporting the Kaweco slogan "Small in the pocket, yet great in the hand". The AL Sport Raw Polished ballpoint is made of solid aluminum, and the refill is extended and retracted by pressing the button on the top of the pen. The available add-on clip, is a nice extra option, especially if you keep the pen in a shirt pocket!
