A picture book with detailed and fun illustrations. A set of two books: "The 100-Story House Mini" and "The Underground 100-Story House Mini." The list price was 900 yen per book. These were my child's favorite books, and they were great for reading aloud, and the mini size was convenient for outings and travel. There is some wear and tear, but they are still in good condition, so I am offering them for sale. I would appreciate it if those who understand that these are used items would consider purchasing them. [I am very sorry, but due to shipping costs, combined purchases with "The Sea 100-Story House" (listed separately) are not possible.]
