In 1921, Sakura Color Products of Osaka, Japan, formulated Cray-Pas® oil pastels with premium quality pigments, wax, and oil. Today, the finest elements continue to make up the Cray-Pas family of oil pastels. Cray-Pas Expressionist® oil pastels are the standard by which all other pastels are measured. The Expressionist colour range allows students, hobbyists, and professional artists to achieve a range of painterly effects. Expressionist oil pastels are extremely smooth to apply, can create broad strokes, and allow the user to blend colours to build texture and depth.
The extender is a colourless oil pastel, further extending any Expressionist colour for the continuation of hues.
