This is a BEN DAVIS card case with a mirror. It could also be used as a business card holder. A mirror is attached to the back when closed, so you can use it to check your appearance. The size is approximately 12.5cm x 9cm when folded. Please understand that there may be some slight variations. It seems like there's a magnet or something inside, allowing it to fold properly. Although it's unused, it has been stored at home, so please purchase it with the understanding that it is a home storage item. Color: Black
