Thank you for viewing. Doraemon Social World - What is the Constitution? - World Geography and Life - Secrets of Ancient Civilizations Doraemon Exploration World - Secrets of the Japanese Language - Amazing! Secrets of Inventions - The Mystery of Dogs This is a set of 6 books in total. - There is a fold mark on the cover endpaper of "World Geography and Life" (Photo ④). - There is a crease on the cover and front cover of "Secrets of Ancient Civilizations" (Photo ⑥). It's difficult to see in the photo, so I've shined a light on it. It's where the diagonal line is. Other than that, there were no noticeable damages, but please forgive me if I missed anything. ▪️ We will disinfect, do a simple cleaning, and take measures against water damage before shipping. ▪️ Anonymous shipping and free shipping.
