Most crayons are made of petroleum paraffin wax.

Crayon Rocks are made from U.S.A.

grown and processed soy wax.

We combine this wax with other plant waxes and a variety of non-toxic powdered pigments to create beautiful colors.

We use 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.
