I am unable to negotiate a price reduction. Kumon materials, 3A, all lessons present. Some pages have dates, check marks, and writing in red pen. There may also be folds and scribbles. These materials have been used by a child, so please purchase only if you understand the above. Those considering Kumon may find these helpful. Please note that I cannot answer questions about the target age or how to use the materials. m(_ _)m ①
