Leuchtturm1917 brings the rotary pencil from the 1920s back to life. Its distinctive shape makes this writing instrument unmistakable: a hexagonal body and a tapered tip that is color-contrasted like the rotary head. The rotary pencil is made from precisely machined aluminum and brass, then painted and sealed. It features a spring-loaded rotary mechanism. The rotary pencil No. 1 is a ballpoint pen with royal blue ink.
