To use these Slash Koi posters and prints, first choose a spot in your room where you want to display them. You can use tape or picture - hanging kits to put them on the wall. When handling the prints, be gentle to avoid creasing the paper. Keep them away from direct sunlight as it can fade the colors over time. If they get dirty, you can use a soft, dry cloth to gently wipe the surface. Don't use any liquid cleaners as they might damage the paper. That's it - enjoy your beautiful Slash Koi decor!
