(From Amazon.co.jp) rOtring was founded in 1928 in Germany, at a time when the designs of the Bauhaus design school were strongly influenced by art and architecture. Based on the belief that "precise lines are beautiful" and the Bauhaus philosophy of "art in industry," the company has created numerous minimalist yet high-performance products. Even as times change, the process of "thinking"—the process of turning ideas into reality—has remained unchanged. Whenever inspiration strikes, you can visualize it and let your imagination run wild. rOtring is always there to support this process, supporting the creative minds of professionals. The Rapidograph Drafting Pen features a "Double Helix" (double air pressure adjustment groove) mechanism to prevent ink overflow. The capillary (capillary fluid system) cartridge system requires no maintenance, as the ink adjustment section is replaced every time the cartridge is replaced. The design minimizes the contact area between air and ink, preventing clogging and hardening even with high-density, ultra-fine particle pigment ink. 0.6mm spare nib for the Rapidograph Drafting Pen.
