Using this Captain America Shield 3D Wall - Mounted Deco Light is super easy. Just find a nice spot on your wall, attach it securely with the provided tools, and then use the on/off switch to turn it on or off. When using, make sure the power source is stable. Avoid touching the LED lights directly with wet hands to prevent electric shock. To keep it looking great, you can gently dust it with a soft cloth from time to time. Don't use harsh chemicals or abrasive materials to clean it, as this may damage the shield or the lights. Enjoy your new Marvel - themed decoration!
