This is a set of 12 main books from "Kodomo Challenge Step" (for 4.5-year-olds) for the year, from the April issue to the March issue. This set includes a year's worth of educational materials. This is an offer for the main books only; no supplements are included. Would you like to use them for home study? Please feel free to comment if you have any questions. 【Condition】 Some books are in good condition as they were not used much, while others show signs of use from being read frequently. However, they should be perfectly readable. Some books with stickers or craft activities may have been used, while others may have some remaining. This varies, so please consider this with the primary purpose of reading the books in mind. They are still in good condition and it would be a shame to throw them away, so if you have a child of the appropriate age, please consider them. I have looked through them quickly and found no writing inside, but there may be some oversight. * One book has a name written on the back cover.
