"Detailed Study of World Heritage 300 ‹ 5th Edition › Official Textbook for the World Heritage Certification Level 2" World Heritage Certification Office Price: ¥2200 I purchased this about a year ago to take the World Heritage Certification. I've used it a few times, so the cover has a slight crease. Also, because it was stored on my bookshelf at home, there's some blackening on the back cover. There are no markings inside. ⚠️Please refrain from purchasing if you are sensitive to items stored at home. 〇Instant purchase is welcome. 〇Negotiations for price reduction are accepted in the comment section.
