Set of 12 educational DVDs for toddlers. (One DVD is the same. Another one was sent because there might have been an initial defect from Challenge. Since it's unclear which one had the initial defect, there are two of the same.) For 4-5 year olds, Kodomo Challenge Step I have kept the DVDs that I enjoyed and watched with interest when I was taking the course for a long time. Some are from different years. I was interested in animals and science, so I kept DVDs related to them, so they are a mixed collection. For those who understand. I have not re-watched them for the listing, so I am not sure if they can all be played without problems, but I will sell them to those who understand. ・The Mystery of the Crow Observation! ・Observation Adventure Start! ・Where Does the Food Go? ・The Mystery of Dinosaurs Observation! ・Where Does Water Come From? ・The Mystery of Dolphins Observation! ・The Mystery of Sound ・Body Mystery Exploration etc. - Target age: For toddlers - Theme: Animals, Adventure, Education - Series name: Kodomo Challenge - Language: Japanese Thank you for viewing.
