This is the Kodomo Challenge Hopp for 3- and 4-year-olds from the 2023 school year. Includes 12 main books. Some stickers have been applied. The educational toys are all shown in the photos. Animal Balance Puzzle: Almost unused, so it's clean. Donut Set: 2 donuts are missing. The donuts themselves are clean, but the accompanying paper items have some folds. Programming series: I believe it's complete. Almost unused. Hiragana Karuta (Japanese alphabet card game): The box is folded, but the contents are clean. The tracing sheets have some pen marks. Everything has been used, so the condition varies, but I hope someone can use them rather than throwing them away.
