That box looks like it's for transporting brushes. You can just store your brushes normall in any cup, mug, cylindrical holder. That way it's easier to reach for your brush and use them.
If you want to use that box for storing brushes, make sure the brushes are dry or else mold will grow in the box. But seriously, it's best to leave brushes out in the open.
