This is a Buffet Crampon Prestige A clarinet. The serial number is in the 700,000 range. I purchased it two years ago from someone who specializes in studying the clarinet. After I bought it, I had it adjusted every six months at a well-known clarinet repair shop in Tokyo, so there are no issues with the instrument. I am selling it because I have upgraded to a higher-end model. However, there is one issue: the instrument and case cover have the new logo, but the case itself has the old logo. This was the case when I received it. Please check my profile before purchasing.
