Temporary signs that really are temporary! Smart Signs and Graphics manufacture magnetic signs which attach securely to metal but are easily and quickly removed when not needed. Used primarily for cars and short-term sales signs, vehicle magnets work really well in many situations.
Perhaps you use more than one vehicle and want the flexibility to use your advert on all of them. Or maybe you have more than one sales message and want to ring the changes in a single location. Magnetic signs fill any empty space.
