I purchased this about 20 years ago, but haven't used it in over 10 years, and it has been stored in an accessory case. I have lost one, so this is a single earring. There is no box, and I don't know the material. I bought it at a department store, but I don't remember the details, and I have no proof of purchase. I will protect it with cushioning material for shipping. Please purchase only if you understand that it is used and that time has passed since the purchase. Thank you for looking.
