Kodomo Challenge Hopp 3 years old, 4 years old October - March, 6 books Picture book materials, bulk sale I also have the 2026 edition, but the content is almost the same ^ ^ Some items may be missing, such as stickers, as they have been used. However, I think the picture books alone are sufficient. They are fun and engaging, covering seasons, short stories, manners, etc., and children enjoy and concentrate on the content. How about trying them out? Shipped via Yu-Packet Post. #KodomoChallenge #3yearsold #4yearsold #Benesse #Childcare #EarlyChildhoodEducation #Childcare #Discipline #Manners #Seasons
