The cello stopper is not just a function to fix the cello tail. We have reduced the performance platform of the concert hall and introduced the acoustic design to make the cello stopper more functional and convenient. The cello stopper is a must-have accessory for all the players who play the cello. The traditional cello stopper is for the cello to play, the tail pin does not slide, but the tail pin is also the resonance of the cello. This minihorn is good for practice, trio, or quartet.Because of the sound hole is open on the side, more stereo sound, more surround feeling. Package: 1x minihorn, 1 x silicon pad, 1 x extend strap
