Clarinet case bag (case cover) Can be used in 3 ways: hand-carried, backpack, and shoulder bag. Fits a standard-sized double case. For Yamaha single cases, B♭ clarinet and E♭ clarinet could be stored side-by-side. (This may depend on the model, so please use this as a reference.) It seems that it can also be used for other woodwind instruments such as flute and oboe, in addition to clarinet. It has been stored for a long time, almost unused. There appear to be no scratches on the metal fittings, but we are looking for buyers who understand that this is a long-term storage item by an amateur.
