Using your metal Christmas nativity scene is a breeze. Thanks to the pre - cut holes, you can easily hang it on your indoor or outdoor wall. Just find a nice spot, use a nail or a hook, and it's up! For outdoor use, make sure to place it in an area where it won't be hit by strong objects. As for maintenance, since it's powder - coated, it's quite durable. But you can give it a gentle wipe with a soft cloth every once in a while to keep it looking great. Avoid using harsh chemicals or abrasive materials as they might damage the finish. If you notice any minor scratches, don't worry too much, as the powder - coat helps protect the steel. Enjoy your beautiful custom metal nativity scene for years to come!
