Heads or tails, you’re gonna love these. Our Spare Change Hoops give off serious coin collector energy with their grooved edge design—like you found the coolest quarter in the junk drawer and made it fashion. Sold as a pair. Materials: 18K PVD Gold Plated Titanium, Titanium Measurement: Interior diameter of each hoop is approx. 20mm.Care: Water- and tarnish-proof with proper care. If exposed to salt water, chlorine, or lotions/perfumes, rinse off with cool water and gently dry. When not wearing, store in a dry, cool place. Do not pull, twist, or tug on your jewelry. Be aware that with clicker style hoops such as this, the post that goes through the ear can get bumped slightly, reducing the secure click to close them. Verify how these earrings fit prior to wearing them. Adjust the ear post slightly by pushing up or down on it, as needed until you hear a click (meaning that your earrings will stay shut!)
