Charcoal Pencil Set features smooth, grit-free charcoal leads that are very black and creamy. Includes two pencils in each of three degrees (Soft, Medium, and Hard). Charcoal Pencils are a form of dry art medium made of finely ground organic materials that are held together by a gum or wax binder, the same as compressed charcoal. The amount of binder used determines how hard or soft the charcoal will be.
