To use these Omni Slash Orb posters and prints, first choose a nice spot in your room to display them. You can hang them on the wall using a poster hanger or a frame (which you'll need to buy separately). When handling the prints, make sure your hands are clean to avoid staining. To keep them in good condition, avoid exposing them to direct sunlight for long periods as it may fade the colors. Dust the prints gently with a soft, dry cloth from time to time. If there are any minor stains, you can use a mild cleaner on a soft cloth to carefully clean the surface.
