These are large earrings. They are unused, but have been stored. (I took them out of the bag to take photos.) I believe the material is synthetic resin. The color appears to change depending on how the light hits them, but the base color is pink. I've taken photos with a measuring tape to show the size, so please take a look. There is no special box, but I will pack them carefully and ship them quickly. Color: Pink, Multicolor Material: Plastic/Acrylic
