Canopus inner mute (inner muffler), dial type. Purchased from the Custome Shop Canopus online shop, but I am selling it because I no longer have the opportunity to use it. I only took it out once to check the condition, and I have not installed it on a snare drum or adjusted the screws. There is no sign of use or any scratches. As shown in the 5th reference photo, the paper part on the top of the package is missing, but the plastic wrapping is still intact. Mounting hole stance: 12mm 【Instant purchase OK】 ※ No smokers, no pets ※ No returns ※ We are not responsible for any problems during transportation.
