No impairment of display representation and touchscreen functionality. You will hardly notice any difference compared to a Nikon D3x without a display protector. Scratch-resistant due to the special hard-coated surface! Very resistant to scratches and abrasion! 4H pencil hardness. Precisely tailored for the Nikon D3x, excellent quality ensured by the use of state-of-the-art precision machines (laser cutting technology) - optimal edge adhesion, very good shape stability. 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 at fair wages in Germany.
