The On-Stage MSB6500 Mic Stand Bag is a heavy-duty nylon bag that fits either 3 round base or 3 hex base or a combination of both microphone stands including shafts and booms. It comes with a heavy gauge 2 pull zipper, so the bag can be unzipped length-wise from the center. Two hand straps ensure a well-balanced load and the deluxe corded piping gives the bag its rigid shape.
