Note: Avoid bumps and friction with hard objects, avoid contact with acidic substances (including skin care, beauty, and washing products), and the organic salts in sweat during exercise can easily cause the surface of the jewelry to oxidize. After wearing, please wipe it with cotton cloth and seal it for storage. Careful care will keep it new for a long time.
