Doremi Music Publishing A set of 3 books of "Children's Bayer," a piano textbook for beginners. These are used, so as the photos show, there are writings inside. The name on the certificate of completion will be blacked out before sending. While there is a sense of use, I think they can still be used. Since this is a casual inspection, there may be oversights. Please refrain from purchasing if you are sensitive to such things. There are individual differences in how usage and stains are perceived. Please understand that these are used items before purchasing. We do not accept claims or cancellations after purchase. If you have any concerns, please feel free to ask questions. Thank you. I am also listing these items elsewhere, so please be aware that I may suddenly cancel the listing if they sell there.
