Manufacturer's description:
"Made of high quality hand-spun aluminum, Jo-Ral trombone straight mutes are designed and tested to perform evenly in all registers. Finished with a copper bottom, this model offers a powerfully dark and rich sound compared with the standard all-aluminium model. The mutes feature neoprene-enhanced composite cork pads that grip well and don’t dry out, become brittle or break off, and so last longer while easily accommodating fine adjustments for a perfect fit."
