Jo-Ral Tenor or Bass Trombone Straight Mute Cork

A better, more durable cork.

Jo-Ral Mute Corks feature a neoprene-enhanced composite. The result is a more pliable cork that grips well and does not dry out, become brittle, or break off, so it lasts longer while easily accommodating fine adjustments for a perfect fit. In an emergency, the self-adhesive design makes for a quick fix.
