Kaweco designed the Dia2 fountain pen to embody timeless beauty like a "DIAmond". It features an iridium point steel nib, a shiny black acrylic body, a solid chrome-colored brass clip, and additional chrome-colored accents including Kaweco logos on the cap and back end. The distinctive knurling on the cap and end of the barrel has been a unique design element since Dia2 was launched in the 1930s. With its screw-on cap, the pen stays securely closed when not in use.
