Shichida Method Brain Development CD - Inu (Young Children) Complete 12-Volume Set - Set Contents: Shichida Method Brain Development CD, Complete 12 Volumes - Media Type: CD - Language: Japanese Purchased at the Shichida classroom. I believe they were about 1,000 yen per volume. All CDs are included. There are traces of name stickers having been removed from the covers. Also, there are stains and scratches on the back covers of June and February. Please refrain from purchasing if you are concerned. I would appreciate it if those who understand and accept these items as being stored at home would purchase them. Shichida Method CD Shichida Method
