Dennis Wick and Bach trombone mouthpieces. This is a set of two and will not be sold separately. Sizes: Bach 5GS rim, inner gold plate Retail price: Approximately 45,000 yen Dennis Wick 4AL silver plate Retail price: Approximately 23,000 yen Both are for large shank trombones. They are in beautiful condition with little signs of use. The selling price for the two is around 68,000 yen, so I think it's a great deal considering their condition. As a bonus, I will also include a Galaxy mouthpiece pouch. It can hold two trombone mouthpieces.
