Details: Introducing Amazingforless tempered glass screen protectors for your I watch 38mm series 1, series 2 & series 3 - whole transparency: The protector is 0.33mm thick and made with chemically treated, transparent tempered glass. - Surface hardness: 9h: The surface of the protector has a hardness of 9h, three times stronger than regular pet film. Even sharp objects will not scratch the protector. - Oleo-phobic coating: The protector has an oleo-phobic coating that prevents fingerprints and other contaminants and makes the film easy to clean. - Delicate touch: The protector is coated on the back with a strong silicon adhesive that makes installation easy and attaches the film firmly so as to not affect the touch screen's sensitivity. - Anti-shatter film: If broken, the protector breaks into small pieces that are not sharp, making it safer than other glass products. Please note: Due to the curved-edge design of the I watch 38mm series 1, 2 & 3 our screen protector is made to be a little smaller than the actual screen of your device. This is to prevent the protector from overlaying these curved edges which can lead to unwanted bubbling and peeling up around the edges.
