I believe these books are children's literature, suitable for elementary school students in grades 2-6. They were purchased at a used book sale from books that were being removed from a library. Some books show discoloration on the covers, but the insides should be free of stains and dirt, so they are in relatively good condition. Please choose two of the children's books pictured (the tall ones). Additionally, please choose one book from the "Flower Bouquet of Fairy Tales" series. If you purchase all 11 books together, the price is 999 yen. Please consult with me before purchasing the entire set.
