These decals have only the design/text computer cut from vinyl and have "empty space" everywhere else. There is no background. The color of the background shows through. The graphics come with a paper backing on the back and application tape on the front. Peel the paper backing from the decal, leaving the graphics stuck to the application tape on the face. Apply the graphics, rub or squeegee in place, then carefully remove the tape from the front of the decal leaving the graphics in place. We send along instructions and will also supply a link to some helpful online videos. Vinyl Decals will last indoors or outdoors and should hold up very well for many years. They are rated as a 6 year outdoor life and will do very well in hot, cold, wet or dry weather. Vinyl decals can be removed from surfaces using a little heat, will not harm the surface and are not reusable once removed. Vinyl decals can be placed on any hard, dry, smooth, clean surface. Most decals are easy to apply with professional looking results. Larger graphics are best installed by someone with a bit of experience with vinyl graphics.
