Swiss made from 1915 to the present day. Caran d’Ache was founded when Geneva had no other pencil maker. The city was filled with watchmakers and jewelers and that atmosphere of detail and innovation affected this company. They designed the first mechanical pencil, invented the first watercolor pencil and their line of pencils, luminance 6901, won a certificate for the highest lightfastness. In all their products there’s care for the environment in which they source materials, the quality of craftsmanship, and the safety and experience of the people whose hands will eventually hold these tools.
