Great art starts with great products. Louis Prang developed child-safe art products that uphold the highest standards of quality in materials and color. These standards are maintained today in a comprehensive line of Prang art products for both children and professionals. Prang Crayons are made from a unique soybean oil formulation. Our crayons are made from 100 percent renewable resources and do not include paraffin wax. This formula makes our crayons brighter and smoother than ordinary wax crayons. All Prang crayons are AP certified non-toxic. The easy-open tuck box is easy to use and keeps crayons stored safely away. Each 64-color box includes fluorescent colors and multiple skin tone colors. Be bold, color your world, and discover Prang power.
