This is a set of 8 books. The 7 books in the box have been stored at home unused. I have flipped through the Kazu no Ki, and the cover is slightly yellowed, but the contents are in good condition. *No individual sales or price reductions. They will be shipped in a recycled cardboard box. I am also selling other Dōgūkan books and products. Please feel free to ask any questions.
