Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is the cap only. The ligature that holds the reed to the mouthpiece is sold separately.
This is the regular version. Inverted Bonade ligatures use a different cap, so match the type you own.
It is sized for standard Bb clarinet mouthpieces. Unusually thick or custom mouthpieces may not accept it.
Yes, if you want the reed and mouthpiece tip to survive being packed in a case. The tip chips easily.
