Kodomo Challenge English educational materials, set of 4 books. Since my child has grown, I am selling these. Each book has content based on a specific theme, allowing children to learn. Please refer to the third photo for a sample of the contents. Each book is filled with hidden pictures, making learning fun. These have been used, so please refrain from purchasing if you are sensitive to this. Thank you! #Benesse #Benesse #English #EnglishMaterials
