These thumbsticks are designed for Xbox One gamers. Use them to replace damaged thumbsticks on your controller or for a mod. They're made of durable rubber with a concaved thumb grip area. The size and grip style are almost the same as the originals. Installing them requires opening the controller, which might void the warranty, and you'll need a Torx T8 & T6 security screwdriver (not included). They come in a 2-pack, perfect for one controller.
