12 piece set of wax crayons for children (and of course adults).
Wax crayons are small pens or markers made from chalk or a chalky substance. They are often used to make temporary markings on various surfaces such as concrete, metal, wood, paper and cardboard, glass, textiles, etc.
They come in various colours, and can often be quickly erased with a damp cloth, although the durability depends on the quality of the wax crayon. They are often used in construction work, removals, inventories, workshops, schools, playgrounds, events and other situations where temporary markings are required.
