The sound is less likely to scatter in the high register. When played fortissimo, it has a more solid sound than the "8". This is being sold to clear out stock. It has only been used for practice a few times. There are some minor scratches from use, but overall it is in good condition. To prevent scratches, it has not been stored in the mouthpiece case of the instrument case. The purchase price was probably around 15,000 to 16,000 yen.
