These are binders for filing Kumon educational materials. 2-ring type, 10 in total. As shown in photos 2 and 3, there are some marks on the spine where nail polish remover was used, but I don't think it's very noticeable. If you are concerned, you can cover them with white tape and write numbers on them, which should solve the problem. There are no other noticeable scratches or marks in other places. They are compatible with Kumon paper materials such as math and English.
