Metal detectable crayons are 13mm x 100mm and come in a corrugated cardboard box of 80 in single colours of black, red, blue, or green.
Metal Detectable crayons are used in the food industry to check misplaced crayons don't contaminate the finished product as they can be picked up when x-rayed. These crayons are used extensively by the seafood/fishing industry on polystyrene boxes under harsh wet conditions.
Other colours are available but minimum quantities will be required.
These crayons have been made in New Zealand for over 75 years. They are a high quality product: non-toxic, asbestos free and highly pigmented.
