Cellist's Companion Stopper A compact, ultra-thin device designed specifically for cellos measures just 10 x 10 x 0.5 cm in size, allowing even the most delicate music to be played without interruption. A gentle vacuum can easily pass over its surface, and its small size makes it difficult for even a curious dog to grasp. Securely fixed with high-quality double-sided tape, this stopper provides reliable performance and peace of mind for musicians on-the-go.
