PAC compressed charcoal is high-quality, natural and soft. It never scratches paper and can be easily smudged or blended. This kind of charcoal is made of finely ground wood (birch) charcoal (50-70%), clay (25-50%), lamp black pigment (3-8%) with a hint of ultramarine (3-5%). Fixative is highly recommended.
Perfect choice for graphic arts, especially for life drawing.
