This is a set of three books in Integrated Chinese (Textbook, Workbook and Character workbook). Great condition. The textbook has very minimal writing in it. The Workbook is filled out partially (L1-L2P1 and L9 P2-L10). It is all written in pencil and can be erased. The character workbook is filled out partially on some and fully on others (see pics for details. Will still work if you need the content.
