TouchProtect Satin - Enhance Tactile Feel, add Style, and Protect Your Trackpads. for Steam Controller and HTC Vive Controllers. Smooth Satin Feel (High Roller)

The title of this product implies that the surface texture of these protectors would feel similar to satin but they are just slick glossy surfaces that make your thumbs stick even more to the trackpads than without them. I seriously could of just found a random sticker I had laying around cut it into two circles and stuck them on my controller for the same effect.
