12.5-inch Laptop Privacy Screen Filter Magnetic LCD Screen Protector

Purchased on Amazon, but the size didn't fit, so I'm selling it. I've discarded the original box, so it will be shipped in a different bag.

[Compatible Models] 12.5-inch (16:9) exclusive privacy filter. (277mm*161mm) Please refer to the 3rd product image for detailed measurement methods. Variation in vertical/horizontal width: +/- 1mm.
[Laptop Screen Privacy Filter] - - The screen appears completely black from angles other than 60° (30° left and right) centered on the front of the screen. This privacy protection filter prevents private information such as emails, websites, IDs, and passwords displayed on your screen from being seen by others when using your laptop outside. The viewing angle is narrowed to approximately 60°. It effectively guards against peeking from diagonally behind.
[Easy Magnetic Attachment] - - The Privacy Filter with Magnets uses the magnetic force of magnets attached to the top of the filter for fixation. Unlike adhesive methods, it can be attached only when needed and easily removed when not in use, making it very convenient.
[Double-Sided Use] Choose between AG (anti-glare) coating to reduce reflections and glare, or a glossy transparent coating for clear visibility. You can select your preferred side according to your preference. Both sides can be freely used depending on the usage environment and purpose.
[Anti-Glare Processing to Prevent Reflections] - - To prevent the laptop screen from becoming difficult to see due to light reflections and glare, the filter surface is treated with anti-glare processing. Reflectivity: 5.8% → Reduces reflections from external light and lighting.
