We are pleased to offer a set of oil crayons like the ones used in Waldorf schools in middles school grades. They are lightfast colors, are transparent and blend well. Students learn many interesting drawing techniques using these crayons. These are the classic Filia Oil Crayons, square instead of round for easy gripping and pointed to make defining features in their drawing easier. The edges or the flat surfaces are suitable for two-dimensional drawing and shading. This cardboard box has 36 different colors, each stick is 2 1/4" long. Made in Denmark.
