I am selling these Joy-Cons because I have too many at home. The green Joy-Con's SL and SR buttons do not work, so it cannot be used as a single controller (it can be used by joining it with another controller). The joystick cover is missing from the light blue Joy-Con. Both have been tested and confirmed to work. Other than the buttons mentioned above on the green Joy-Con, they function well. Please purchase if you understand that these are used items.
