Unused. I am selling it because I no longer need it. Lifeinnotech 16-inch (16:10) Magnetic Privacy Screen Protector Filter, LCD Screen Protection Film (6mm wide magnetic sheet type) Blue Light Cut, Anti-Reflection, Double-Sided Use, Easy to Attach and Detach 【Compatible Models】 16-inch aspect ratio 16:10 Dimensions: Filter part only 346.5 x 218 mm (vertical/horizontal variation: +/-1mm). The black magnetic part at the top is about 6mm. The screen may appear slightly blurred due to the difference in height between the screen and the bezel. 【Privacy Protection】 Protects your screen from prying eyes while you're on the move or in the office. This is a magnetic privacy filter that can be easily removed. 【Double-Sided Use】 The surface has a matte texture with low reflection, and it is an anti-glare surface (anti-reflection processing, non-glossy) that is easy to see even in places with strong fluorescent light. The reflection rate is 6.5%, which reduces surface reflection from lighting and external light, improving screen visibility. 【Blue Light Cut】 This LCD screen protector significantly cuts "blue light," the blue portion of the light emitted by LED LCD displays. 【Scratch Prevention】 Because it uses a material with high surface hardness, it is resistant to scratches and can firmly protect the screen. In addition, it is resistant to sebum, dirt, and dust, keeping the screen clean. *Incompatible models: Some Lenovo ThinkPad series models (ThinkPad X390, Yoga, X1 Carbon, etc.) may cause the screen to not display due to malfunction of the sleep sensor when the filter is attached. In that case, it may be improved by adjusting the position of the magnet away from the sensor.
