If you're concerned about your future health, a privacy filter with blue light and UV cut is recommended. ⭐ This privacy filter can be used on both sides. The glossy side has higher light transmittance and is suitable for viewing high-resolution videos and images. Use the glossy side if you want to enjoy clearer images. ⭐ The other side (matte side) has a matte texture and anti-reflective processing, which reduces reflections from fluorescent lights. Use the matte side in areas with windows or many fluorescent lights. ⭐ Although there is a difference in the surface, the privacy protection effect is the same on both sides. You can use it according to your environment. ※ Note: If the screen appears dark and difficult to see after installing this film, adjust the brightness of your computer. 【Size】 13.3 inches (16:9) Width 294 mm × Height 166 mm Compatible brands: HP, Lenovo, Dell, Acer, ASUS, Samsung, Envy, Toshiba, etc. ※ Please check the detailed dimensions in advance, as the size may vary depending on the model, even with the same inch size. 【About Shipping】 Anonymous shipping. ※ We will use the cheapest shipping method, so please understand that the packaging will be simple. 【Notes】 ◆ We inspect the products, but please note that there may be minor scratches. ◆ The actual color may differ slightly from the product image. ◆ Returns and cancellations due to customer reasons, such as size or image differences, are not accepted. ※ If there are any defective products after the product arrives, please contact us before 【rating】.
