To use this Lilo & Stitch jewelry set, simply put on the necklace by fastening the chain around your neck. Adjust the extender if you need a longer fit. For the earrings, just open the earring backs and clip them onto your ears. When not in use, store the set in a jewelry box to prevent scratches. Clean the pieces gently with a soft cloth to keep them looking shiny. Avoid exposing the jewelry to harsh chemicals like perfume or cleaning agents, as they can damage the gold color and the pendant.
