This is a bow case for a contrabass. It can hold two bows, either German or French. It comes with a shoulder strap, allowing you to carry the bow case on its own. There's also a pocket where you can store rosin, a tuner, and other accessories. I'm selling it because I've replaced my case and haven't been using this one as much. It's recommended for those who want to carry both their main and secondary bows at the same time.
