Denis Wick Bell Mask for Trumpet or Cornet

The Denis Wick trumpet or cornet bell mask was developed to help reduce the risk of spreading harmful airborne droplets and aerosols. This cover easily fits over the bell and does not restrict the sound of the instrument. Although there might be a very slight difference in response in the high register, the sound remains true from low to high. Excellent for school ensembles, amateur bands and professional brass sections alike. Fits 4.5" bells.
