Using your new mosaic metal round mirror is a breeze. Just find a suitable wall space in your living room, bedroom, or hallway, and hang it up. Make sure the wall can support its weight of 23.2. As for cleaning, use a soft, dry cloth to gently wipe the mirror surface to keep it shiny. Avoid using abrasive cleaners as they may scratch the mirror or damage the satin black finish. Since this product contains nickel, keep it out of reach of children who might put it in their mouths. If you live in California, be aware of the potential cancer - causing risk associated with nickel as mentioned on the warning. Regularly check the hanging hardware to ensure the mirror stays securely in place.
