The e65S is a mouthpiece characterized by its e-rim (wide and flat), and I imported it personally because it's not sold in Japan. It cost me about 70,000 yen. First of all, it's a model that's rarely available in Japan. The size is about a 3 to 5 in Bach terms. Because of the flat and thick rim, it's less tiring even with hard pressing, and the efficient GR design makes it easy to produce both low and high tones. I used it once in a performance, so it's almost new! There are no scratches that would hinder playing!
