Want a keychain you can play? How about a keychain you can play that has lots of parts? The Aggravation Keychain from Basic Fun is the answer... It has a big game board, a dice, 20 mini marbles, and even a little tweezers to move the marbles with. And it's practically a party in itself... up to four people can play your Aggravation Keychain at once. The idea is to move your four marbles across the board to Home before your opponents. Yeah, it might be tiny. But there's a lot of fun packed inside this little thing!
