Using this mirror is easy. You can choose to hang it horizontally or vertically according to your room layout and personal preference. When hanging, make sure to use appropriate wall - hanging hardware that can support its 42 - unit weight. Keep in mind that this product contains nickel, a chemical known to cause cancer in California, so handle it with care. For maintenance, use a soft, dry cloth to wipe the mirror surface regularly. Avoid using abrasive cleaners as they may scratch the mirror or damage the iron frame's satin black finish. If the frame gets dirty, you can use a mild soap and water solution to clean it gently, then dry it thoroughly.
