◆ For Dell Inspiron 16 7620 2-in-1 【Surface Strength: 9H】 With 9H tempered glass, this product thoroughly protects the LCD screen from cracking and is hard enough to resist scratches even when a cutter is applied. 【Oil-Repellent Coating】 The oil-repellent coating prevents oil, fingerprints, and dirt from adhering, keeping the screen beautiful. In addition, it is easy to wipe off water droplets, sweat, cosmetics, etc., and provides excellent finger滑り感. 【2.5D Round Edge Processing】 The R-shaped processing (rounded edges) of the edges rounds the edges, which are a weak point of glass films, and disperses pressure from all directions. It also prevents the finger from catching during operation and provides an outstanding fit. 【Airless Processing】 Using a special silicone adhesive that prevents air bubbles from entering, it is very easy to apply and difficult to peel off, and it does not affect the sensitivity of the screen. Thank you for your consideration ☺︎
