The Protec genuine leather bass bow quiver is thoughtfully constructed; the opening is reinforced so it doesn't collapse shut when the bow is out. There is nothing more frustrating that a bow quiver that defeats its own purpose by closing itself, so you have to aim, wiggle and stab your bow into it in the middle of a tune, looking like you're trying to take a blood sample. Enjoy peace of mind on stage with this quality quiver that is always programmed to receive.
Note: the top opening has more defined corners so it's kind of a triangle shape. Hard to see in photos.
