In 1761, Kaspar Faber started to produce pencils in Stein, near Nuremberg. When the fourth generation,Baron Lothar von Faber, took over the company in 1839 he turned the pencil into a true quality product and the world's first branded writing instrument. Over the centuries, he and his descendants created remarkable products. The result is the Graf von Faber-Castell Collection, a range of extraordinary writing instruments and accessories. They embody "Luxury in Simplicity" by combining selected materials, functionality and superb aesthetics.
