Size: long ear hook about 6cm, no ear hook 5cm / width about 3.5cm Material: electroless brass, jade, hollow gray glass, stainless steel ear pin (can be changed ear clip) - Maintenance method: 1. Pure brass will not fade, but it will be oxidized by contact with air and moisture. It is not suitable for bathing. If it is not worn for a long time, it is recommended to put it back in the zipper cover provided at the time of purchase to isolate the air. 2. Use a toothbrush to rub the toothpaste. After gently brushing the brass bracelet, wipe it with a dry cloth to make the jewelry rejuvenate around 70%. 3. No pearls/shells, etc., can be mixed with white vinegar + water (ratio 1:1), soaked for 30-60 seconds, then washed and dried, then you can rejuvenate about 70%. (It is not recommended to use silver-washed water for maintenance. The silver-washed water will corrode the brass surface and cause damage to the bracelet and stone.) - Precautions: 1. Each computer is different, the consideration may produce a slight color difference, and the actual entity still needs to be based on commodity entities. 2.
