Our Stickeeez! are made with high quality vinyl, the same material they use for stripes on boats and airplanes and cars. This vinyl has a high-strength, permanent adhesive that will last for many years outside and even longer if used inside. They come with application material already applied and a set of instructions to help them go on as smooth as possible. The image will be only what you see in black, there is no clear background. Whatever you apply it to will be the background color.
For best visibility, use light colors against dark backgrounds and dark colors against light backgrounds. Usually lighter colors show up better on glass and car windows.
