This was attached to a bag, but I haven't used it, so I've been storing it. It has rings on both the left and right sides, so it seems like it could be used as a pochette if you attach a shoulder strap, but there wasn't one originally. If you have a shoulder strap, please use it. Size: Approximately 17cm (height) x 30cm (width) x 7cm (depth) The design of the inner lining is cute. It has an inner pocket and a zippered pocket. Please refrain from purchasing if you are concerned or are a perfectionist.
