3mk ARC. The 3mk® ARC protects the entire surface of the rounded screen from edge to edge. Its clear and even structure perfectly reproduces colors and ensures excellent finger glide on the screen surface. The 3mk® ARC is the first high-quality dry-installation protective film that is applied to the phone's surface without any liquid. Thanks to its memory material and self-healing properties, it adheres perfectly and can smooth out scratches. Installation is made easy with Fit-In™ positioning stickers that accurately place the 3mk® ARC on the screen.
