The Charcoal Sketch Set contains 2 Pitt Natural Charcoal sticks (6-11mm), 1 Pitt Charcoal Pencil medium, 1 Pitt Pressed Charcoal pencil soft, 1 Pitt Pastel pencil white medium, 1 kneadable eraser, and 1 paper wiper. The natural charcoal sticks glide softly across the paper, rub, and smudge easily, and can be erased without difficulty and repeatedly overlaid. The charcoal pencils leave a much blacker line.
