Backpack-type wheeled carry bag, used 2-3 times, some issues Purchased from a certain Chinese e-commerce site and used about twice for domestic business trips. It's a convenient bag that can also be used as a backpack, but the telescoping handle has some issues; as shown in the photos, it can extend, but it requires a knack. If you can't extend it, you can press the stopper inside the zipper to extend it, so you can use it once you confirm the location. Please check the photos for the size and weight. Will be sent in compressed packaging.
