This is a NIKE large-capacity backpack from the Y2K/00s era. Size: Approximately 43cm (height) x 53cm (width) x 20cm (depth) The sides can be further expanded by opening the zippers. This item is from the 2000s. Some of the nighttime fluorescent material on the front belt is missing. There is some blue rust on the zipper of the left pocket (when viewed from the front), which may have slightly reduced its smoothness. Please check the photos for details. The black-based design with the NIKE logo stands out and is perfect for casual styles. It's an item that's easy to use in any situation. It would be great for travel, school camping trips, school excursions, camping, etc. Of course, it can also be used in everyday life. Thank you.
