You, me, or nobody is gonna hit as hard as life. The understated Box Chain Bracelet is the champion of daily wear. The square box chain links have a classy timeless look that can be worn dressed up or down. The clean square silver chain links are a classic favorite. 925 Sterling Silver. Oxidized & Polished Finish. Lobster clasp closure. Nickel free. Handcrafted in Korea Sterling silver naturally tarnishes when exposed to salty air, chlorine, sulfur, humidity, perspiration, cosmetics, household bleach and other strong chemicals. To remove any tarnish, we recommend routinely wiping your sterling silver jewelry with the polishing cloth included. Regular wear of LOUPN sterling silver jewelry can also help prevent tarnishing as the oils in your skin help keep Silver from oxidizing faster. Remove heavy tarnish with warm water, mild soap and a clean, soft cotton or flannel cloth, a special sterling silver cleaning cloth or a very soft-bristle brush like a baby toothbrush. Silver polish or dip-style cleaning solutions are NOT recommended. When not in use, please store the design in the provided pouch with the anti-tarnish tab.
