Silent Brass STX-2 and a pickup mute for euphonium. I bought it new and used it only a few times for practice at home to recover my skills, so it's almost like new. Everything in the photos is included. It sells for around ¥38,000 to ¥39,000 new. I don't have the original box, so I will ship it in a different cardboard box. Although it is in good condition, please understand that it is a used item before purchasing.
