Highly pigmented pastels developed for the professional and serious artist. Nearly all of the colors possess the maximum possible resistance to fading. They adhere well onto paper, card stock, wood and stone with minimum fixing. Square shape allows you to make a wide variety of strokes. Although they are firm they are still easily blend with finger or stomp. Polychromos Pastels also exactly match Polychromos Colored Pencils and Albrecht Dürer Watercolor Pencils for multimedia works.
