Taguchi Wind Instrument Workshop, MASAKI U-ST. This is a French horn mouthpiece. The photo looks gold, but it's silver-plated. This item is currently out of stock and unavailable for purchase as of the listing date. I felt it was a mouthpiece with a straightforward and responsive feel. The inner diameter has the same specifications as the one I usually use, so I think it's the difference in the rim shape, but it felt a little large for me and didn't fit, so I would like to sell it to someone who can use it. There are no noticeable scratches except on the shank. U-STU Cup 17.50mm 4.20mm Silver plated American shank Thank you for viewing. Please understand that this is a used item before purchasing.
