The DUX DUCIS Leno is a privacy screen protector designed specifically for the 15.3-inch MacBook Air models from 2023, 2024, and 2025. It uses a specialized PET film and private glass that turns the display black when viewed from angles greater than 30 degrees, ensuring your work remains hidden from onlookers in public spaces. This protector attaches via nano-vacuum adsorption, which means it stays in place without the use of glue, magnets, or sticky adhesives. Because of this design, you can easily detach, wash, and reposition the film whenever needed. The material is built to be scratch-resistant and shock-resistant, providing a layer of defense against daily wear while maintaining a bubble-free fit. Each set includes a storage clip to keep the protector safe when it is not in use.
