This metal Celtic Irish Shamrock wall art is a great addition to your St Patrick's Day decor. To hang it, you can ask us to add hanging holes for free when you place your order. Then, just find a nice spot on your wall and use appropriate wall - hanging hardware. As it's made of 16 - gauge steel and powder - coated, it's quite durable. But avoid scratching the surface with sharp objects. For maintenance, you can simply wipe it with a dry cloth from time to time to keep it looking good. Don't expose it to extreme humidity or moisture for long periods to prevent any potential rusting.
