This is a single case for an A clarinet. As far as I know, there are hardly any single cases for A clarinets, and even if there are, they are usually B♭/A dual cases like those from "Schwenk & Seggelke" or "Reed & Squeak" that only use cushions and don't secure the instrument. This instrument case secures the clarinet, preventing it from rolling around inside and reducing stress on the keys, allowing for safe transport. Confirmed to fit a Buffet Crampon R13 (see photo 1). Other manufacturers have not been confirmed. The photos show the case I am currently using; the item for sale is new. Made in China, so there may be some minor scratches from the manufacturing process. No returns or exchanges accepted. I will ship as quickly as possible after payment is processed, but there may be delays due to work. If you need it urgently, please comment. *This listing is for the instrument case only. The instrument itself is not included.* *It's difficult to tell from the photos if it's an A clarinet case, so I've included photos with a B♭ clarinet inside (photos 4-7).* As you can see in the photos, it's an A clarinet-specific case, and there is extra space when a B♭ clarinet is placed inside. External dimensions: 200mm x 350mm x 110mm Case weight (excluding instrument): 500g
