Purchased in August 2024 and used until mid-November. After that, it was stored in a Ziploc bag in a dark place. I am selling it because the size I use has changed. There are minor scratches from manufacturing and wiping, and marks on the shank from being inserted, but it is generally in good condition. It can be used for trombones as well as euphoniums.
