DescriptionCompressed Charcoal is made from a scorched blend of black, wood ground charcoal, gas and Chasov Yar clay. It is a soft-medium grade, producing even coverage. Measures 4-3?8″ in length and varies in thickness. #19101 Set of 50 Natural Willow has changed from a wooden box to a hangable, transparent, snap-to-close plastic box. Easy to clean and great for reuse after your charcoal is gone.
