How to wear: Simply open the lobster clasp and put the necklace around your neck. You can adjust the length between 16.5 and 17.5 inches to fit your preference. Notice: Avoid contact with chemicals like perfume, lotion, or cleaning agents as they may damage the 24K gold plate and the imported glass. Maintenance advice: Clean it gently with a soft, dry cloth after each use. Store it in a jewelry box to prevent scratches and keep it away from direct sunlight and high humidity.
