These Super Marshmallow Bros. posters and prints are easy to use. Just find a nice spot on your wall, and use tape or a frame to hang them up. Make sure the surface is clean and dry before hanging. When it comes to maintenance, keep them away from direct sunlight to prevent fading. If they get dirty, you can gently wipe them with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials on them.
