Note: The screen protector is intentionally cut smaller than the display, as the edges are curved. There is no impact on display clarity or touchscreen functionality. You will hardly notice any difference compared to an Oppo Realme C15 without a screen protector. Scratch-resistant due to the specially hardened surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Intentionally smaller than the Oppo Realme C15 glass, as it is curved (see photos), bubble-free and can be removed at any time without leaving residue (no adhesive). Easy installation! No bubble formation possible on a dust-free display! When applying the film, the air is displaced and it adheres to the display as if by itself. Can be removed at any time without leaving residue! Made in Germany - construction, cutting, and finishing done at fair wages in Germany.
