I believe this item is unused, but the box shows signs of age, such as damage and scratches. I purchased this at a used goods market. It should contain 10 sheets per box, but there are 14. I have no knowledge of musical instruments, so please refer to the images before purchasing. 【Important Notes】 ● No claims, no returns, and no support. ● If you do not contact me within 24 hours of winning the auction, your order will be cancelled. ● Please make payment within 3 days of starting the transaction. ● I may not be able to answer specialized questions. ● I do not ship on weekends or holidays. ● I generally use recycled paper bags and cardboard for packaging.
