 5. Maintenance method of alloy jewelry:
 6. Usually, you should always replace it when you wear it. Don't wear a piece of jewelry for a long time. Especially in summer, the sweat you contact every day may cause a certain degree of corrosion to the jewelry, which has an impact on the service life of alloy jewelry.
 7. When wearing alloy jewelry, do not contact with chemicals, otherwise the jewelry will be damaged. Do not wear alloy jewelry for swimming, because the chlorine in the swimming pool and the salt in the seawater will damage the jewelry.
 8. When alloy jewelry is not worn, pay attention to the storage environment, and do not put it together with other jewelry.
