To wear these Sand Bar Wave Hoop Earrings, simply open the hoop and place it on your earlobe. They look great with both casual and formal outfits. When not in use, store them in a jewelry box to prevent scratches. Avoid exposing the earrings to harsh chemicals, such as perfume or cleaning agents, as this may damage the gold plating or the opal crystals. You can gently clean the earrings with a soft, dry cloth to keep them looking shiny.
