Faber-Castell 129903 Pitt Compressed Round Charcoal Sticks in supreme artist quality. Grease and oil-free material. Intensive blackness. It's a very soft application. Degree of hardness: soft. Natural charcoal sticks are the oldest sketching and drawing material in the world. The greyish-blue shade glides softly across the paper, rubs and smudges easily, and can be erased without difficulty and repeatedly overlaid. Their blueish hue has always held a fascination, even with the old masters. Charcoal sticks leave a much blacker line. Compressed charcoal with soot and clay gives the charcoal pencils their deep black colour and can be produced in different degrees of hardness.
