Using your studded black mirror is a breeze. You can hang it either horizontally or vertically according to your preference and the space you have. Just find a suitable spot on the wall and use appropriate hanging hardware. As for maintenance, use a soft, dry cloth to wipe the mirror regularly to keep it clean and shiny. Avoid using abrasive cleaners as they might scratch the matte finish. Remember, this product contains nickel, so take care not to damage the frame or mirror surface to prevent any potential exposure to the chemical.
