Body Jewelry, regardless of the material, will require an extra care as the material is inserted into the flesh. We recommend the followings. - Always remove jewelry when performing heavy sweating exercise, swimming, and showering as any substances like water, oil, chlorine, perfume, and sweat may damage the jewelry. - Always use warm water and mild soap if you need to clean. Never use alcohol or any chemicals as they may cause discoloration or other adverse reactions to the jewelry. Always dry your body and jewelry thoroughly before reinserting. Be sure to use soft non-abrasive cloth to avoid scratching the metal. - If you have had any reaction to the plated jewelry (i.e., necklace, bracelet, rings, etc.), we do not recommend any plated jewelry as you may have a similar reaction. - We recommend placing your jewelry in a zip closed bags when not in use. - We take hygiene seriously, please note we cannot accept returns on used body jewelry
