These chains are made from either solid brass or copper or an alloy of both. The base metal is electroplated with a high quality gunmetal plating and have a lobster clasp.
Please note: This chain is not recommended for sensitive skin or if you plan on working out in your jewelry. Excessive sweat and/or exposure to water will eventually cause the gunmetal coating to wear away. This chain is great for everyday (dry) wear and should be removed before working out, showering, or swimming. If you require a chain that will withstand your workouts, we highly recommend the stainless steel link or stainless steel bead chain. Sterling silver is also good for sensitive skin (unless of course you have a sterling silver allergy).
