To use these posters and prints, first decide where you want to hang them. You can use nails or adhesive strips to hang them on the wall. When handling, be careful not to touch the printed surface with dirty hands to avoid stains. For cleaning, use a soft, dry cloth to gently wipe the surface. Store them flat in a dry place if you're not using them. Don't expose them to direct sunlight for long periods as it may fade the colors over time.
