Kaweco designed the Dia2 roller ball pen to embody timeless beauty like a "DIAmond". It has classic styling, with a shiny black acrylic body, a solid brass clip, and additional gold-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. The pen contains black ink, and refills are available. With its screw-on cap, the pen stays securely closed when not in use.
A black gift box is included.
