Thank you for viewing. This is an SM4XR euphonium mouthpiece. There are scratches on the surface, but I don't think it will affect its use. Please refer to the fifth photo for the size, etc. The current list price is 35,200 yen, so I will sell it for half price. I will consider a small discount, so feel free to comment. The following is a quote from the description: This mouthpiece was created through the development collaboration of world-renowned euphonium player Steven Mead and Missa Mead. It is the XR series, which further evolved the popular euphonium mouthpiece "Ultra 4X". The rounded rim, new inner shape, and slightly shallower cup depth provide a better playing feel, which can be described as a "sports model". It has great potential in the high range, and the ease of playing and transparent tone provide a new playing feel. The mid-range is even more powerful, and in the low range, the sound is very clear due to the different sound weight from the conventional "ULTRA X", which will add power to each phrase.
