There are two missing books. The following supplements are included: - 2nd Grade Kanji Poster - Glittering 2nd Grade Free Notebook - Multiplication Table Kanji Battle Machine - Multiplication Table Kanji Battle Machine Instruction Manual - 4 DVDs These items have been used by a child, so there are signs of use, scratches, and stains. The cover of the August issue of "Hatenna? Hakken! Book" is severely torn. The cut-out parts and stickers inside have been used in 5 out of the 10 books. The DVDs have one in poor condition, two with minor scratches, and one in good condition. The free notebook and poster are unused, but they are not in perfect condition as they have been stored at home. The Multiplication Table Kanji Battle Machine has been confirmed to start up with batteries inserted. Please feel free to inquire about selling individual items.
