Our shop's gold-plated jewelry uses eco-friendly nano mirror coating technology. The material is a mixture of brass and gold plating with an added protective layer on the surface, effectively extending the lifespan of the jewelry. This product is resistant to high and low temperatures, non-toxic, greatly reducing the allergy rate. The appearance closely resembles gold color at 90%. Please rest assured when purchasing; our shop defaults to shipping via YTO and Yunda Express. If not delivered, we will default to postal service with Yunda and YTO Express. The jewelry can be worn for 1 to 3 years without fading (if it darkens over time, you can clean it with toothpaste)
