I design it myself and make it carefully. 【Material&Specifications】 The length of the chain is 45 cm. Materials:silver925 This product is handmade, and so may not look exactly the same as the photo. This product will be shipped by regular air parcel. Please avoid wearing silver jewelry when taking a shower/bath, swimming, or using a spa or hot spring. Otherwise the silver will turn yellow over time and restoration will not be possible. If silver becomes tarnished as a result of discoloration or oxidation, please use a silver cloth and wipe the jewelry in one direction. This should restore luster to the silver. To avoid oxidation, when not wearing, wrap your silver jewelry in tissue papers and put it in a plastic zipper bag.
