These are Cartoon Y2K UFO Acrylic Earrings. They measure approximately 1.50X3.35 inches. They are green and black. Depending on the light they may look yellow or blue. They are acrylic, so they are light weight. They are see through like glass. They have a hook enclosure. I have 3 pair available. These are sold locally at my store, The Vixen boutique LLC. All sales are final and price is firm.
