Like new, these earrings are in perfect shape as shown in photos. Bought directly from seller, just trying to pare down my collection. The lighting is mostly filtered sunlight from the window. As shown in the last couple photos, they measure approx 1.77" in length including the stud. R2D2 is some kind of lightweight metal, and I'm pretty sure the studs are a faux acrylic moonstone, but I'm not positive on what either material is. Comes from smoke-free home and will be sure to package carefully so it arrives safely. Check out my other listings to get bundle discounts! :)
