Quantity: 4 tempered glass with cleaning kit

Material: Ball-resistant glass for Samsung Galaxy A40, made from the latest high-tech material :::::: Thickness: 0.26mm. Tempered, tempered glass. Touch screen sensitivity is not affected.
Hardness 9H: Due to the extremely resistant surface, the screen is not affected by sharp objects. The protective glass has a hardness of 9h; Industry's leading hardness, providing maximum protection against dirt and scratches.
Surface: Oil resistant (oleophobic), water and grease do not stick to the protective glass. This armor film provides solid protection for the touch screen and provides excellent protection for the flat part of your monitor, providing the right place for almost any case.
Blister-free and without fingerprints: The installation is very easy. Thoroughly clean the display with the supplied dust cloth to ensure a dust-free and perfect application. At the touch of a button, the protective film is bubble-free and exactly mounted on the display. The air bubbles are removed automatically because the protective glass is automatically connected to the screen.
Placing the screen protector on the built-in display makes it much easier to place the glass correctly!
Note that hardened glass is slightly smaller than the phone's non-conducting screen because the phone's screen has a curve.

Make sure the mobile screen is 100% clean because if dust is present, the air bubble will be below the hardened glass.
