This is the Nintendo Switch game Ring Fit Adventure. It includes everything: the Ring-Con, leg strap, etc. I received it from a friend, but I'm selling it because I don't use it. It's been opened. My friend used it for about a year after purchasing it. I haven't used it at all since receiving it. It was working about a year ago. I haven't re-tested its functionality this time. The game software and Ring-Con are in good condition. The leg strap has some lint. Also, the outer box has dents and folds. Please understand that there may be other signs of aging as well.
