Please refrain from price negotiations. Regarding the "Nazenani Book" I purchased this as a full member of Katei Hoikuen (Home Daycare), but the spines have faded because they were kept in a room with good sunlight. Also, the pages, when viewed from above, show what appear to be stains typical of used books. I didn't use them much, and some have never been opened, so I think the contents are clean. However, I haven't checked them in detail, so please refrain from purchasing if you cannot accept any oversight.
