This is a Selmer ligature. I used it for a tenor JodyJazz HR (hard rubber) mouthpiece. As you can see in the photos, there is rust on the inside. This is a used item, so please refrain from purchasing if you are sensitive to such things. No claims and no returns accepted. [As of December 26th] I will be away from home during the New Year's holiday, so it will take about a week to ship the item.
