Left only. -------------------- The left stick is defective (moves on its own). The right stick also occasionally feels off. Charging and attaching are not a problem. There are no scratches, but the blue one has faded slightly. It's still usable, as it doesn't prevent operation, but I'm selling it because I bought a new one. The straps are unused. Please understand the above before purchasing. Only those who can repair it or understand the condition are welcome. Selling each side separately is also possible. In that case: Left (Blue) 1400 yen Right (Red) 1900 yen Joy-Con Left Right Blue Red Red Blue Nintendo Switch Joy-Con Strap
