PU Leather Anti-Slip Grip Decal for Logitech MX Master 3s Mouse – Durable, Sweat-Resistant Sticker Set – Improves Handling and Comfort – Mouse Grip Tape Accessory ※Please note that this is not the mouse itself. Please degrease the surface thoroughly before applying. I was able to apply it without any problems to a new mouse, but when I used it on a mouse I had been using previously, the thumb grip started to peel off gradually. Thank you for viewing.
