This item is for 50 Black Thumbsticks (25 sets) for Xbox 360 controllers. Change the look of your own controller by adding custom accessories! These are Microsoft's original Black Thumbsticks, not 3rd party. Great replacements for your existing thumbsticks, and easy to install. They simply pop on/off when your controller is taken apart. You will need a T8 Screwdriver to take your Xbox 360 controller apart (which we have).
