Dycem Black Hole Cello and Double Bass Endpin Stopper

The 'Black Hole' endpin stopper or 'Donut' as it is more commonly called, is one of the most popular stoppers on the market. It has a very simple design and is covered in a non stick material which is very effective on smooth surfaces. We do not recommend the use of this product on carpets as it picks up fluff which causes it to lose its stick. Can be used with or without a spike protector.
