The pastel is a perfect pencil companion to soft pastel because its lead is slightly harder with less pigment It is preferable to Conté soft pastels and crayons when details are required for small and medium-sized formats. In contrast with soft pastels, pastel pencil should not be added in successive layers of colors but used as pure colors laid out in patchwork fashion side by side These large diameter pencils have very fine, smooth leads that are rich in pigment. The presence of abrasives provides excellent toning and stumping qualities. Use Conté pencils to obtain a precise mark or line on a variety of papers. Pencils are pre-sharpened.
