Also popular: A set of 5 Kaiketsu Zorori books! All purchased new at the bookstore at the regular price. Please purchase only if you understand that these are used books that my child has read. There is some slight wear on the corners of the covers, but all covers are present. I have done a quick check, but I have not checked every page completely. There are scratches on the covers and a general feeling of use, but they are in relatively good condition. Thank you for your consideration.
