Stop your cello or bass from sliding around! Invest in a non-slip endpin stop, especially if you're playing a cello or bass on wooden floors.
Made by a company that specializes in non-slip rubber products, the Black Hole Cello/Bass Stop is a simple and effective means of holding the cello in place - the smoother and harder the floor, the better it works. Just place the Black Hole in position and let the unique non-slip properties do the rest. No messing around with strings or belt straps around the chair legs! Easily carried in the pocket or in the case.
