These square pastels are made by Derwent, manufacturer of quality art materials since 1832. The square shape allows the artist to use the ends, sides and edges for different effects. There are 24 beautiful colors plus a blending white. The colors can be used individually or blended together and the soft texture makes for interesting effects. They can be used with Pastel Pencils to add detail and highlights. This set is suitable for any level of artistic skill and makes a wonderful gift. PLEASE NOTE: Despite careful packing pastel sticks are sometimes subject to breakage during shipping and handling. Professional artists recognize this as common to these products but that it does not affect their usability or results.
