These waxed round cake cardboards have been coated with an FDA approved waxed coating on one side to make them grease-resistant. Easily wipe away frosting without stains or grease marks!  Un-waxed & cake boards marketed as "grease resistant" still show grease from cakes, cookies, and desserts. Check out the difference in the piped rose picture after only 24 hours! The board on the left is a waxed cardboard. The board on the right is an uncoated cardboard.
