Thank you for viewing. This is a single semi-hard case for a B♭ clarinet by bam. Model number: TREK3027S Suggested retail price (excluding tax): 38,000 yen (Please note that this is not a double case) I accidentally bought this thinking it was a double case, so I am selling it brand new, unused, with tags. 2-way: Handle and backpack The backpack straps can be stored as shown in the second picture.
