Imperfect Subtraction Equations

These are just like our first quality cards except there is a slight production error that made us judge it as second quality (no typos; no missing cards). The error may be that the colors are slightly off, the images slightly askew, a spot or small hair in the laminate on one or more cards, and/or a slight curve to the laminate. Often the error is only on one card and customers can't find it (but we can)! Other than that, these are perfect and complete. Our production error means big savings for you!
