Jewelry maintenance: 1. Jewelry should be changed frequently. The same piece of jewelry should be avoided being worn for a long time, especially in the hot summer. The plating of jewelry is easily eroded by prolonged exposure to sweat, so it is best to have multiple pieces of jewelry to alternate between 2. Contact with chemicals can easily damage jewelry. The scent of bath products, chlorine in swimming pools, and salt in seawater can cause corrosion to the jewelry's plating, so all jewelry should be removed before bathing or swimming 3. It is prone to scratches upon collision, so be careful when storing. Do not stack the jewelry on top of each other; they should be kept in their original packaging bags or placed in jewelry boxes with separate compartments to avoid scratching the surface from mutual friction 4. Clean the jewelry regularly, using a soft fine-bristled brush to sweep and wipe the surface of the jewelry to remove any surface stains 5. Apply a layer of transparent nail polish to the metal surface, which can prevent the jewelry from coming into contact with air, allowing it to be worn for a longer period of time
