Yamaha YAMAHA Custom 31 Rim Gold Plated Horn Mouthpiece Retail Price: 14,850 yen Engraving: YAMAHA Custom JAPAN 31 Rim + Inner Gold Plated (24K Pure Gold) Overall, I believe it is in relatively good condition. There are some minor scratches and shank wear due to use, but I did not feel any hindrance to playing. *Please check the images for details* 《Specifications》 ・Rim Inner Diameter: 17.28mm ・Bore (Throat): 4.4mm ・Cup Depth: Medium (Standard) ・Rim: Medium Wide (slightly wider) ・Features: "The medium rim shape has the flexibility to meet advanced musical demands. The slightly wider throat diameter allows for a rich, slightly darker tone and high volume." Due to the gold plating, the mouthpiece feels smooth on the lips, making lip control easier, and it is easier to obtain volume even with relatively less blowing force. Also, it has a rich and heavy tone, and I think it is a well-balanced mouthpiece that is less tiring even during long hours of playing. Considering the condition, I am selling it for less than half the retail price. If you are looking for one, or if you are interested in purchasing, please consider this opportunity. *Due to the nature of the mouthpiece, unavoidable minor scratches may exist due to contact during instrument attachment, care, cleaning, and wiping. Also, I have confirmed that these do not affect the performance at all before listing. If you are looking for a perfect item like a new one, or if you are particular about details, please consider carefully before purchasing. I am selling it at a low price considering it is used, so please understand this point. Thank you for your understanding and consideration. [French Horn]
