Stockmar wax crayons meet the highest artistic standards. Through the addition of pure beeswax as a binding agent, the light-resistant pigments display their purity and full brilliance. Because they are mixed with wax, the colors are able to be used in a wide range of interesting coloring techniques - more than any other coloring material. The natural transparency of the wax and the lack of additives result in a high degree of opacity like that of watercolors.
