These decals are made of vinyl. They can stick to any solid surface. Please note that if the vehicle is exposed to the sun/the elements, the integrity of the decals cannot be guaranteed. If the decal is left on for an extended period of time and the vehicle is left out in the sun, the paint beneath the sticker might not get sun-bleached alongside the rest of the paint, meaning once the decal is removed, there may be a silhouette of what was once there.
 
The price for these varies greatly, as the decal needs to be designed, and then, depending on the complexity (the amount of different colours) and size, the decal will determine the final price of the sticker. The cost can be anywhere from $25.00 to $250.00.
