I believe I've used it once. I think it can be used for both black formal wear and everyday use. Size: Approximately 20.8cm x 29cm x 11.5cm Please allow for slight variations. The entire back is a pocket. Inside, there is a pocket with a zipper and two regular pockets. There is a scratch on the bottom right of the front, so please check images 7 and 8.
