I purchased this several years ago on Rakuten to practice for my child's music recital at home, and it has been stored at home since then. There are stickers indicating the pitch of the notes. You can remove them if you wish, but there may be some residue left behind. Please check the photos. This item is intended for practicing the pitch of xylophone and glockenspiel notes, so please refrain from purchasing if you are concerned about the sound being musically out of tune.
