This work has the appearance of metal plating or electric spray paint, but it will wear out after long-term use or heavy use. To ensure the longevity of gold-plated items, please store your jewelry in a dark, cool, and dry place, such as a small bag or airtight box, and avoid rubbing the gold-plated items together. In addition, please try to avoid contact with cleaning products and perfumes that may have a negative impact on your items.
