NOTE: The screen protector is deliberately cut smaller than the display because it is curved at the edges. | No impairment of the display representation and the touchscreen function. You will notice virtually no difference to an Oppo K9s without a screen protector. | Scratch-resistant due to the special hard-coated surface! Very resistant to scratches and abrasion! 4H pencil hardness. | Deliberately smaller than the Oppo K9s glass, since this is curved (See photos), bubble-free and can be removed at any time without residue (without adhesive) | Easy installation! No bubbles possible with dust-free display! When applying the film, the air is displaced and nestles as if by itself to the display. Can be removed at any time without leaving any residue! | Made in Germany - Construction, cutting and finishing at fair wages in Germany.
