I am unable to negotiate a price reduction. Kumon materials, 4A, all lessons present. Lesson 101 has a pen marking, which has been cut out. I apologize for this. Some pages have dates, check marks, and writing in red pen. There may also be folds and scribbles. These materials were used by a child, so please purchase only if you understand the above. These materials may be helpful for those considering Kumon. Please note that I am unable to answer questions regarding the target age or how to use the materials. m(_ _)m
