This bag can be used in 2 ways by removing the shoulder strap. When used horizontally, it can fit a 500ml plastic bottle. Although small, it has a wide interior like a Boston bag, so it can hold a lot of luggage. I purchased this for 12,000 yen and used it a few times, but I'm selling it because I haven't used it recently. The tag surface is torn. Please check the images. No bag included. Please refrain from purchasing if you are concerned, as it has been stored at home by a private seller.
