To use these prints and posters, simply find a nice spot on your wall where you want to display them. You can use regular wall - hanging tools like nails or adhesive strips. When handling the prints, make sure your hands are clean to avoid getting fingerprints on them. To keep them in good condition, avoid exposing them to direct sunlight for long periods as this can fade the colors. Also, try to keep the area around the prints dry. If there's a little dust on the print, you can gently use a soft, dry cloth to wipe it off.
