Thumbsticks Replacement for Xbox Series S X
The anti-skid overlay for the analog stick is made of TPU from the Xbox Series S / X console - a combination of plastic and rubber.
The cap is definitely harder than the silicone one, it fits very well to the mushroom, it does not significantly increase its size
The cover is not a replacement part - it is not intended to replace the damaged rubber layer on the plug. It is put on an efficient, complete mushroom.
