Precisely tailored for the Sharp Z3, excellent quality ensured through the use of state-of-the-art precision machines (laser cutting technology) - optimal edge adhesion, very good shape stability. No impairment of display visibility or touchscreen functionality. You will hardly notice any difference compared to a Sharp Z3 without a screen protector. Extremely scratch-resistant due to the specially hard-coated surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Easy installation! No bubble formation possible on a dust-free display! When applying the film, 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 at fair wages in Germany.
