This is a tenor/bass trombone case by Kühnl & Hoyer. I purchased it used along with the trombone itself, but I'm selling the case only, as I'm using a different case. A backpack strap is included. When not in use, the strap can be stored inside the zipper and won't get in the way. Some discoloration can be seen on the metal fittings, but it doesn't affect use. There is no major damage to the interior. There is a pocket on the outside of the case that can store a music stand, etc., which is convenient. It's a semi-hard case, but it's very lightweight. I plan to ship it via Yamato Transport.
