To use these Oogie Balrog posters and prints, just find a nice spot on your wall. Clean the wall surface first to make sure the poster or print sticks well. When hanging, be gentle to avoid creasing. As for maintenance, keep them away from direct sunlight to prevent fading. If there's dust, you can use a soft, dry cloth to gently wipe them. Also, try to keep the area around them dry to avoid any damage.
