DVD set of two: "Mr. Gobo's Health Exercise: Self-Exercise Edition" and "Mr. Gobo's Health Exercise: Oral Exercise Edition" by Hiroshi Yanase, also known as Mr. Gobo. *Used a few times at a facility, but no longer needed, so I am selling them. *The inside of the case for the Self-Exercise Edition is dirty. *Please refrain from purchasing if you are sensitive to used items, as they have been stored at home.
