I purchased this about four years ago and used it for about two months, but it didn't suit me, so I stopped using it. There are no noticeable scratches, and there are no problems with playing. The outer box has a large scratch, but there is no concern about safety (see image 4). I will clean it again before shipping. This is a mouthpiece developed by the tuba player of the orchestra, Shinpei Tsugita, in collaboration with the popular Romera Brass. The base adopts a V-cup that follows the Helleberg style, and combined with Romera Brass's smooth surface processing, it achieves an extremely comfortable airflow. The rim diameter is slightly smaller for this style, preventing excessive air consumption and improving control performance. The appearance is also unique and beautiful, and the sound quality boasts excellent playability due to the appropriate weight control. Inner diameter 32.50mm / Throat 8.25mm
