This is a Vandoren B40 bass clarinet mouthpiece. I bought it in my third year of high school, but I only used it for a year and have kept it in storage since I bought a new one in university. I won't be using it anymore, so I'm selling it at a low price. Regarding the condition, there are traces of a patch and some minor scratches on the patch area and sides. I have disinfected and cleaned it with a mouthpiece cleaner. Also, it has been stored at home, so please understand this before purchasing. Although I don't have the original box, I will pack it carefully with cushioning material. The current retail price is 34,650 yen, but since it was used for one year and stored at home, I'm selling it for less than half price. I will consider price reductions as much as possible. Please comment. Thank you for your consideration.
