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 blue Joy-Con's joystick cover is missing. Both have been tested and confirmed to work. Aside from the aforementioned buttons on the green Joy-Con, everything else works fine. Please understand that these are used items before purchasing. Thank you.
