A set of two books: "The Truth About the Extremes That Corrode Japan," published in 2018, and "The New Solar System," published in 2007. I've read them about twice and kept them on the bookshelf. The covers have some folds, etc., but I think the inside is in good condition. ★Please purchase if you understand that these are used items and have been stored at home. #Tsunehira Furuya #Jun'ichi Watanabe
