These Stay Puft posters and prints are easy to use. Just find a nice spot on your wall, use some tape or picture hangers to put them up. Make sure the surface is clean and dry before hanging. When it comes to maintenance, avoid exposing them to direct sunlight for long periods as it may fade the colors. Also, keep them away from moisture to prevent damage. If there's dust on them, you can gently wipe it off with a soft, dry cloth.
