To wear this necklace, simply open the lobster clasp and fasten it around your neck. The 2.5-inch extension allows you to adjust the length for a perfect fit. When not in use, store it in a jewelry box or pouch to prevent scratches. Avoid exposing it to harsh chemicals like perfume or cleaning agents, as they can damage the gold plating. You can gently clean it with a soft, dry cloth to keep it looking shiny.
