Faber-Castell Pitt Natural Charcoal Pencil Medium
Natural charcoal is the oldest sketching and drawing material known to mankind. The greyish-blue shade glides softly across the paper, rubs and smudges easily. It can be erased without difficulty and repeatedly overlaid. The blueish hue has always held a fascination, even with the old masters. Can be sharpened with a sharpening knife.
