Material Material: Pure Brass (Unplated) / White Turquoise Every natural pearl is not a perfect circle. ⭐️ If you need to customize, or change the type of natural stone, you can contact the designer! Brass maintenance method Usually use a copper cloth to wipe, or use toothpaste or tooth powder to wash with water. After cleaning, be sure to wipe the jewelry completely dry with a cloth. If you do not need to wear, it is recommended to store in a sealed bag. No electroplated flavonoids, no fading or allergy problems. Only the flavonoids are unplated metals. After wearing, they will contact with sweat, cosmetics or the moisture in the air, and will show a retro feeling. Many girls buy lol for the color after oxidation. If you like the bright color, you can follow the above practices. I can't accept the feeling of being a bit retro. Please do not buy it. Thank you! Attention Attention: 1.
