Using this sign is super easy. Just find a nice spot on your wall, line up the holes, and use small nails or screws to hang it. Make sure the wall is clean and flat before hanging. As for maintenance, a gentle wipe with a dry cloth every now and then will keep it looking shiny. Avoid using harsh chemicals or abrasive materials as they could damage the gloss finish. And that's it - enjoy showing off your love for Celtic FC with this great sign!
