Magnets are 4 inches tall or wide. Your photo will be retouched as needed to make it as clear and vibrant as possible. The photo is cropped so the subject is enlarged so it will be 4 inches tall or wide in the finished magnet. All the background in the photograph will be removed. Magnets have a glossy, clear coating to protect it from normal wear and tear and fading. Can be wiped clean with a cloth dampened with water or alcohol. The base material is 1/8" thick white acrylic plastic. Two 1/2" high-strength ceramic magnets are attached to the back of the cutout. These magnets stick far better than the flexible magnets found elsewhere. They will even hold up Junior's school artwork! WARNING Photo cutouts are NOT TOYS and should be kept from small children. Small parts can break off and cause a choking hazard.
