To use these Kingdom Sora posters and prints, first, find a nice spot in your room or office where you want to display them. You can use tape or poster putty to hang them on the wall. If you prefer, you can also put them in a frame later, although frames are not included. When it comes to maintenance, keep them away from direct sunlight as it can fade the colors over time. Avoid getting them wet. If there's a little dust on the poster, you can gently use a soft, dry cloth to wipe it off. Enjoy your unique Kingdom Sora decor!
