Note: The screen protector is intentionally cut smaller than the display because the edges are curved. There is no impact on display quality or touchscreen functionality. You will hardly notice any difference compared to a Fireboltt Ring 2 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 Fireboltt Ring 2 glass due to its curvature (see photos), bubble-free and can be removed without residue at any time (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 without residue at any time! Made in Germany - construction, cutting, and packaging at fair wages in Germany.
