This item is unused. It comes with a shoulder strap, but I can only confirm one place to attach it. It was placed together, so I assume the strap is part of the set, but I don't know how to use it. There is a small bag attached to the main bag. Please examine the main bag, the attached bag & strap in the photos, and only purchase if you understand. No claims and no returns. The item will be shipped using either air cap (bubble wrap) or recycled cardboard for packaging.
