Precautions for jewelry maintenance 
 1.Avoid contact with chemical substances:  
 Alloy jewelry is easily oxidized when in contact with chemical substances, so it should be avoided as much as possible.
 2.Use warm water when cleaning:  
 When cleaning alloy jewelry, use warm water. At the same time, do not soak the jewelry in water for too long to avoid affecting the surface texture of the jewelry.
 3.Avoid friction and collision: 
 Alloy jewelry is easy to scratch and deform, so when wearing jewelry, pay attention to avoiding friction and collision with hard objects.
 4.Store jewelry properly:  
 When not wearing alloy jewelry, put it in a dry box or bag to avoid contact with air and oxidation.
