Thank you for viewing. This is a black NIKE drawstring bag. It's made of nylon fabric and has a small gusset at the bottom. The drawstring holes have metal hardware, making it a sturdy construction. I bought it new and only used it once for a school event (town exploration), and it has been stored since then. Therefore, there are some fold creases. Approximately 33cm x 43cm, gusset (bottom only) approximately 3.5cm. Please understand that there may be slight errors due to amateur measurements. I have checked the item before listing it, but please be aware that I may have missed small tears or stains. Please refrain from purchasing if you are looking for a new-like item. Returns are not accepted.
