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 by courier is included, so no price reduction is possible. Please note that the music sheet holder will be folded in half for packaging.
