This is a set of two books from the popular "Oshiri Tantei" (Butt Detective) series. These picture books are packed with humor and mystery, making them a big hit with children and perfect for reading aloud. They are fun to read and help develop imagination and observation skills. [Product Contents] * "Oshiri Tantei: Murasaki Fujin no Ango Jiken" * "Oshiri Tantei: Yamiyo ni Kieru Kyojin" Both are hardcover books published by Poplar Publishing. The covers show signs of use such as folds, scratches, and wear (especially the red cover has some damage), but the text is generally in good condition and does not interfere with reading. Recommended for children's reading debuts and for collecting the series. Not sold separately, only as a set. ⸻ #OshiriTantei #Troll #PoplarPublishing #ChildrensBooks #PictureBookSet #ReadingAloud #ChildrensBooks #ElementarySchoolBooks #ToddlerPictureBooks #MysteryPictureBooks #PopularSeries #EducationalPictureBooks #ReadingAloudPictureBooks #HumorPictureBooks #EducationalPictureBooks #PictureBookSale #KidsWhoLoveBooks #EarlyChildhoodEducation #ReadingWithChildren #ReadersWhoLovePictureBooks
