Thank you for viewing my item from among many others. This is a Vandoren clarinet mouthpiece, B45 Profile, selected by Mr. Iku Ikematsu. According to the manufacturer's description, compared to the Traditional model, the angle of the beak's exterior is slightly sharper, resulting in differences in breath flow and control. It is said to give the impression of being easier to blow than the Traditional model. The item has been used infrequently, and the cork condition is also good. I believe there are no noticeable scratches or stains. This is an item that can still be used for a long time. Thank you for your consideration.
