Crayon Rocks are made in the USA from a Kosher soy wax, combined with natural mineral pigments to create beautiful colors and a natural ground rock that gives the crayons their body. This creates a crayon that goes on smooth and blends easily. This cotton muslin bag contains 16 colors: red, pink, blue, sky, green, grass, dark yellow, light yellow, orange, peach, purple, light purple, brown, tan, black, and gray.
