Vandoren 5RV Clarinet Mouthpiece This mouthpiece was used for three years in junior high school and then stored unused for four years. It has been cleaned, but there are traces of a patch, ligature marks, and dents. The cork is not significantly deteriorated and can be used without any problems. The globally popular 5RV Lyre is a fundamental model when comparing it to other models. It has a relatively small tip opening, making it easy to play with a comfortable blowing feel. It is easy to control and allows for stable playing from high to low registers. This is the mouthpiece that many students and beginners overwhelmingly start with. I selected this from several mouthpieces at a musical instrument store. The model number is difficult to see in the photos, but it is a 5RV Lyre.
