Castell 9000 pencil in 12-pack: 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H and 5H. The spread of this pencil also contributed to dark green succeeding in becoming the company color for the Faber-Castell brand. It is coated with environmentally compatible water-based paint, a technology which Faber-Castell was the first manufacturer to introduce.
