Boston Bag HARMONINA This bag comes with a detachable shoulder strap for easy carrying. - Color: Navy Blue - Style: Boston Bag - Strap: With shoulder strap (detachable) - Pockets: 1 inner pocket 1 outer pocket on the front 1 outer pocket on the side - Size: Medium Bottom... 20cm (height) x 38cm (width) Height... 24cm Thank you for looking. This size is convenient for a few days' trip. The outer material is nylon, so I think it's okay even if it gets wet in the rain. The material and shape are sturdy and stand on their own. I used it a few times for 1-2 night trips, but I haven't had a chance to use it recently, and it has been stored in the closet. I would be happy if someone could use it. ^_^
