This is a Buffet Crampon B♭/A clarinet double case. It's lightweight and easy to carry, reducing the burden on your body. I purchased it at the end of last year, and since I transported it in a large backpack when using it, it looks very clean. I will include the backpack straps, a pouch, and a rain cover. I am selling it because I will be using a case from another company.
