This is Masaya Kobayashi's "Tarikishiko: Other-Power Thinking for 10x Results at Maximum Speed." It comes with the obi (sleeve). Used once after purchase. I creased about 7 pages at that time (see photo 10). Therefore, it is listed as "Slightly damaged or with stains." Other than that, it's clean. I would appreciate it if you could purchase it understanding this point. [Product Details] "Tarikishiko: Other-Power Thinking for 10x Results at Maximum Speed" Masaya Kobayashi Instant purchase OK!
