Box of 12 Nature Carré Cretacolor pastels Unbaked chalk pastel bars guarantee brilliant color results due to complete pigmentation and a special lightfastness. All shades can be mixed with each other, blended and painted with water. They are characterized by a particularly smooth and grease-free line. The wide side of the chalk is ideal for working on large areas, the edges for crisp lines and precise contours. Fixation is necessary.
