Invented by a US teacher of children with special needs as an aid to fine motor development: Soya Crayon Rocks - easily gripped and easy to use. Made from Soya beans. Safe and non-toxic.
The Nawaro Wax Crayons in 12 vibrant colours are made from natural and sustainable waxes and other materials.
Crayons are safer, non-toxic, easier for children to work with, and less messy than paints and marker pens.
