This is a collaboration item between Prima Instruments and Porter, which is no longer sold. It can store a single or double clarinet case. The original price was 42,900 yen. I'm selling it because I haven't used it recently. Although minor stains are noticeable in the photos, it's a high-quality bag, so I don't think they're that noticeable in person. It can be used as a backpack. Shoulder straps are not included.
