This 12 piece pack contains 4 sticks of small, medium and large diameter width Charcoal. Willow Charcoal is softer and lighter in colour than compressed charcoal and can be used alone or with other drawing media. May be smudged and blended with fingertips or a paper stump. Willow Charcoal may be erased with a Mont Marte Kneadable Eraser to reveal highlights. Suitable for all levels of artistic levels. Spray finished work with fixative to avoid smudging, or use tissue paper as a divider when storing art work.
