Regarding Condition: The internal adjustment parts have been removed and are not included. (I discarded them because I preferred less resistance.) I purchased this 7 years ago. I used it for about 3 years and then stored it at home. There are some mysterious, faint stains on the rubber parts. Product Description: A practice mute that's the talk of the town for its excellent cost performance, amazing muting capabilities, comfortable blowing feel, and pitch accuracy. https://www.nonaka.com/information/detail.jsp?id=32326
