Vandoren M30 Clarinet Mouthpiece I used this for three years in high school and then stored it unused for three years. It has been cleaned, but there are traces of a patch and ligature. The cork isn't significantly deteriorated and can be used without any problems. The globally popular M30 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's easy to control, and you can play stably 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.
