It is a replacement stick for the C-Button for your Gamecube controller's.
Changing the stick is very easy, you just have to open the controller with a Triwing screwdriver, remove the precedent and put this one. You must push strictly to make it fit. And need to turn it 180° if it didn't fit this way. And must push strictly again.
I have also gray stick for the left joystick on my shop.
Condition : NEW
Brand : Generic
I have a lot game/accessories for retro and recent consoles on my shop !
