This bag is not a shoulder bag, but it can be worn over the shoulder. As shown in the 6th photo, there is some minor scuffing on the corners of the bottom. Please consider this before purchasing. It's large enough to easily hold four 500ml plastic bottles. There are also large pockets on the outside and inside, and some areas have zippers, making it convenient. I am also selling this item elsewhere, so please comment before purchasing to confirm availability.
