Trombone/Euphonium Mouthpiece 51C4L Large Shank Silver Plated Thank you for viewing. I used it once, and disinfected it properly at that time. I bought it a long time ago, but I take care of it at the same time as other mouthpieces, so although there is some feeling of use, I think it is in relatively good condition. I would be grateful if you could purchase it after checking the condition in the images. Also, I will offer a discount if you purchase it together with other products. Thank you.
