This is a set of 11 "Kodomo Challenge Step (for 4-year-olds)" books. They haven't been read much, so they are in good condition. Some books still have stickers. Some stickers and supplements have been used, but there are months where the books haven't been read at all. Please refer to the photos. Since a child has read them, there may be some minor bending, so please be aware of that. Some of the "Step Newsletter," "Shimajiro Newspaper," and a clock poster are included (as shown in the photos). #KodomoChallenge #KodomoChallengeStep #ShimajiroEnglish #EarlyChildhoodEducation #EducationalMaterials #CorrespondenceCourse #Shimajiro #EarlyChildhoodEducationSet #BulkSale #ExcellentCondition #UsedEducationalMaterials #PictureBooks #EducationalMaterials #IntellectualEducation #LearningMaterials #StayAtHome #PlayAtHome #4YearOldParenting #5YearOldParenting
