I bought Cra-Z-Art crayons at Wal-mart because I couldn't find crayola. I figured a crayon is a crayon, right? Wrong... They color...but leave behind a super waxy residue. So much so, that if you smudge your finger across the area that was just colored, the crayon flakes right off! So, save your money and just get crayola. Discount crayons aren't worth the savings.
