Thank you for viewing. This is a listing for the now-discontinued Happy Time. I gave the first volume to a friend, so it's not included. When my children were young, they attended the Shichida Method. It became difficult to continue attending after my youngest child was born, so we used Happy Time to continue the Shichida Method at home. The DVD content was excellent, comparable to the lessons. Even now that they are elementary school students, my children still remember the DVD content. I believe it is effective for right-brain training. Also, the picture books and print materials included in the set are linked to the DVDs, and the curriculum was well-structured. This is highly recommended for those who are interested in early childhood education but find it difficult to attend classes. DVDs from volumes 8 to 12 are unopened. Volumes 4 and 5 have some minor stains on the cases. The DVDs themselves played without any problems. The picture books are in very good condition as they were used for reading aloud. All the print materials have been copied once. They are in clean condition without any writing. Overall, the items are in good condition, but please consider that they are used, so please understand before purchasing.
