Thank you for viewing. This is a rare Seydel 6-hole harmonica. It is likely the product from the following website, currently out of stock, and a high-priced item with a new price of around 100,000 yen. https://www.themusicstand.ca/products/seydel-concerto-star-6 The included accessory is the case. There are no noticeable scratches or stains. I apologize, but I am unfamiliar with musical instruments, so I have not checked the sound. I have only confirmed the appearance. If you have any other questions, I will answer them to the best of my ability, so please feel free to ask. Please understand that this is a used item.
