The Fixpencil was the world's first mechanical pencil! Invented by an engineer in Geneva in 1929, it was released a year later and has been a success worldwide since. This special edition was the result of a collaboration with Alfredo Häberli, a Swiss-Argentinian designer who has long used the Fixpencils in his work in international design. The two tone body, the aluminum sharpening cap, and inclusion of four water-soluble color leads are just a few of the unique elements of this limited edition Fixpencil.
