What is an unused code for Crayola's color me?

Hi,

An code for something such as crayolas color me is for a prize when you buy two packets of mccains smiles which is chips made into a smiley face. there are codes in the packs where you can go on the wbsite and collect crayola prizes such as pens.

An unused code is a code that hasnt been used yet.

I hope this helped! x
