Crayon Rocks

Most crayons are made of petroleum paraffin wax. Crayon Rocks are made from U.S.A. grown and processed soy wax.
The brand combines this wax with other plant waxes and a variety of non-toxic powdered pigments to create beautiful colors. Crayon Rocks uses a natural ground rock to give the crayons their body. This creates a crayon that goes on smooth and blends easily and is, in many ways, much like an oil pastel.
