It is a replacement stick 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 yellow stick for the C-Button in my shop.
