Faber-Castell - Innovation from Tradition. The origins of Faber-Castell date back to 1761, when carpenter Kaspar Faber began producing pencils in Stein near Nuremberg, which his wife sold at the Nuremberg market. By the 19th century, the foundation for conquering the global market was laid with branches in trading metropolises like New York and Paris. During this time, the company also received its current name, Faber-Castell, through a noble marriage. Today, the company is the world's largest manufacturer of graphite and colored pencils, with production facilities in nine countries and over 8,000 employees, offering a wide range of stationery and paper products. The company places great importance on social and ecological sustainability. Since 2010, 95 percent of the wood used has been certified according to strict FSC standards, and thanks to its own forests, Faber-Castell is recognized as one of the few companies in the writing instrument industry as climate-neutral.
