Connect the Nintendo Joy-Con wrist straps to the Joy-Con and then attach them to your wrist to use motion controls. When holding the Joy-Con sideways, you can also conveniently use the SL and SR buttons. Depending on whether the wrist strap is attached to the left or right Joy-Con, the button will change from SL button to SR button. Wrist straps can be attached to both the left and right Joy-Con. The controllers can be distinguished by the minus and plus signs. The Joy-Con connect via a rail. The wrist straps can be secured close to the wrist with the stopper to prevent losing the Joy-Con while playing. The player display shows the play number of a Joy-Con. The sliding lock prevents the wrist strap from slipping off the Joy-Con.
