The PANDAFLY Compressed Charcoal Sticks set holds 12 sticks: 4 soft, 4 medium and 4 hard. PANDAFLY says the charcoal is fired at high temperatures and gives a velvety pure black.
The listing describes square sticks with a large flat surface for shading large areas, and says you can sand a stick to a fine point for detailed work.
Based on the manufacturer's Amazon listing.
An even split of grades. In general, harder charcoal gives lighter marks and softer charcoal gives the darkest blacks.
The square sticks have a wide flat side for shading big areas in one pass, and the edge draws lines.
Rub a stick on sandpaper to shape a fine point when you need edges or small details.
PANDAFLY says the compressed pure black charcoal produces a velvety surface.
The listing says the sticks are erasable and blendable, with great tonal value. It names studies and life drawing as uses.
The set is listed as non-toxic, and PANDAFLY says it suits budding artists and amateurs of all ages.
