This is a listing for a set of two optional accessories for the trombone case released by DAC. ① B4 size music sheet holder It can hold a considerable amount of sheet music. It is also detachable, and attaching it provides cushioning between your back and the case, making it comfortable. Retail price: 3850 yen ② Mouthpiece pouch It can store three trombone mouthpieces. It attaches inside the case with Velcro and is very convenient. Retail price: 3190 yen Both are compatible with the Sa-Si series, NX-1s, and NX-2. Both have little signs of use. I think they are in good condition. Shipping via宅配便 (takuhai-bin) is included, so I cannot offer a discount. Please note that the music sheet holder will be folded in half for packaging.
