A very high quality compressed charcoal available in 3 degrees of hardness. It is manufactured by compressing and firing charcoal, clay and a binding agent. Depending on the mixture, the resulting degrees of hardness are: 2B = soft, 4B = medium and 6B = hard. 
A higher degree of blackness compared to natural charcoal is achieved through better adhesion to the paper. 

A lead clutch holder can be purchased separately.
