The product is described as "Real Gold-Plated" in the title, but based on the material properties, it is made of zinc alloy with an electroplating process. This means it is not solid gold; it's a base metal coated with a layer of gold. Gold-plated items can potentially tarnish over time with exposure to air, sweat, or chemicals, depending on the quality of the plating. For confirmation of durability or authenticity, consider requesting samples or using Midddleman's quality control services during procurement.
