Supervised by GACKT This is an authentic Extra Release product. I've only used it for about 15 minutes, so I'm listing it as "like new," but it's practically brand new. I can't find the instruction manual right now, so please assume it's not included. If I find it, I will include it. The basic operation is just pressing a button, so you shouldn't have any trouble figuring out how to use it even without the manual. From the website: Accelerating the beauty of all mankind! The "GACKT Kirei Project" has launched! The first item is a "new-age electric stretch roller" that easily stretches the muscles of the entire body.
