For Artists, art students, and people with creative hobbies. Wonderful dry stroke, just like charcoal or chalk. Can be mixed and blended dry. Brilliant results also on dark backgrounds. Its high degree of pigmentation guarantees great luminosity and opacity, as well as permanence and color brilliance. 4.4 mm lead diameter. Can draw perfectly on delicate paper thanks to its soft lead. The wooden body protects the lead from breakage. Partially water-soluble: the outlines remain visible.
