This is an official product. I threw away the bag, but it's unused. It was only kept in my room. It has several pockets inside, so I think it could be useful for carrying goods during live performances. Please understand that this is an overseas product, it's unused but not new and unopened, and it has been in someone's possession before you purchase it.
