Student artists love the bright, vivid colors of these quality oil pastels from the makers of Crayola products. Creamy consistency and smooth blendability. Dry mixing colors will create true secondary colors. Colors will also layer easily without a waxy, crumbly buildup. Water-soluble formula allows students to add water for interesting depth and blending effects: dip them in water to use as paint sticks, wet the paper before drawing on it, or brush your drawing with a wet brush. They can also be used successfully for Sgraffito designs. 24 colors per set. Round sticks measure 3" long by 1/2" wide. AP Seal, non-toxic.
