① The Complete Guide to Input: Maximizing Learning Efficiency ② The Complete Guide to Output: Turning Learning into Results Author: Shion Kabasawa Publisher: Sanctuary Publishing Used a few times, but I think it's in relatively good condition. There is a tear in the paper band of "The Complete Guide to Input," but there are no noticeable stains or scratches on the main body. Please check the condition in the photos, and if you understand that this is a home-stored item from a private seller, I would appreciate it.
