Note: The screen protector is intentionally cut smaller than the display, as the edges are curved. Scratch-resistant, hard-coated surface with 3H pencil hardness. Very good reduction of reflections. Minimizes annoying glare and reflections on the display. The matte anti-glare film has a paper-like surface. Deliberately smaller than the Rinsmola 1.69-inch smartwatch glass, due to its curvature (see photos), it can be removed without residue at any time (no adhesive). Easy application - 100% bubble-free installation on a cleaned display! The special silicone adhesive layer displaces air during application and adheres smoothly to the display. No impairment of usability! The Dipos screen protector offers a pleasant touch experience and is optimized for the Rinsmola 1.69-inch smartwatch.
