This is a jewelry case for a Cartier ring. I kept the case after purchasing the ring, without using it. It's almost new. Size (cm): Width: 10 Length: 8 Height: 4 *Measured flat, please allow for some error. The outer box was on display and has some scratches and stains, so please consider it as an accessory. Please purchase only if you understand that this item has been stored at home by a private individual.
