This is a Hanon staff paper notebook and a Czerny pocket notebook. ○ The pocket notebook has graph paper (5mm) instead of staff paper. The size is approximately 12cm x 8cm. Thank you for viewing. I have kept it at home unused after purchase. There is some sun fading and scuffing on the cover, but there are no folds or writing. These are staff paper notebooks and pocket notebooks that faithfully reproduce the "Piano Library" music score series published by Zen-Ongaku Publishing. They are printed using special music paper and ink made for the Piano Library. #StaffPaper #MiniNotebook #MiniMemoPad
