The body and tip of a crayon is made from a single piece of non-toxic wax.
Non-toxic
Non-toxic means that there are no harmful irritants, poisons, or chemicals included in its composition.
Wax
Wax is an organic chemical compound that is malleable (easily shaped and formed without breaking) and which has a low melting point. Wax is water resistant and used in many manufacturing processes. Children’s crayons are similarly made from non-toxic wax.
