Pure brass (unplated) / Emperor stone / agate / sea sapphire ⭐️Every natural pearl is not a perfect round. If you need to customize, or change the natural stone type, you can contact the designer! Size selection Size: If you want to compare it, it is recommended to +1 (cm). If you want to wear a looser or drape, it is recommended to +1.5 ~ 2 (cm). E.g: The size of the hand is 15 cm. If you want to get together, it is 15+1=16 (cm). All bracelets and necklaces in the store can be used for children's size, the price is extra, welcome to ask for a private message. Brass maintenance method Maintenance: Usually wipe with copper cloth, copper oil, or with toothpaste or tooth powder. Always wipe the jewelry completely dry with a cloth after cleaning. If you do not need to wear it, it is recommended to store it in a sealed bag. There is no electroplated brass and there is no problem with fading. Only brass is an unplated metal. When worn, it will feel a retro feeling due to contact with sweat, cosmetics or moisture in the air. Many girls buy lol for oxidized color. If you prefer a bright color, you can follow the above instructions. I can't accept a little retro feeling, don't buy, thank you! Attention: 1. The goods are hand-made. The production and delivery will not start until the order payment is completed. The production time is about 1-3 working days (excluding the delivery time). Please be patient. 2. Each natural stone has its own unique texture, color and size are not necessarily the same, may contain impurities or small cracks, etc., and can not be exactly the same as the products in the photo. ⭐️If you need to modify after receiving the goods, you need to pay the back and forth postage!
