Kodomo Challenge Hyogen Plus (Expression Plus) - 10 books for 2-3 year olds - 11 books for 3-4 year olds I subscribed to the Kodomo Challenge optional materials every month, but I couldn't use them because I was using other materials. I have excluded 2 books for 2-3 year olds and 1 book for 3-4 year olds because they were used. The items I am selling are unused. If you are taking the Kodomo Challenge main course, the price is 545 yen (including tax) per issue (as of September 2025). If you are not taking the main course, the price is 838 yen (including tax) per issue. I will not sell individual books. Thank you for looking.
