Aramid fiber iPhone case. Only tried it on once. Please only purchase if you understand that it will be sent with minimal packaging. The following is the Amazon description: 【High-Grade Aramid Fiber Material】The Benks ArmorAir case uses high-strength DuPont Kevlar 600D aramid fiber, also used in aerospace and military fields. It has lightweight yet strong properties and achieves a smooth texture that fits comfortably in the hand. The high-quality finish elegantly complements both everyday use and business settings. 【Light as air, strong as steel】The Benks ArmorAir case achieves an ultra-thin design with a thickness of only 1.1mm and a weight of 19-22.2g, adding almost no extra bulk. It maintains the optimal slim silhouette for an iPhone 17 Pro case without compromising portability. Furthermore, the raised camera ring and reinforced edges provide excellent protection against scratches and impacts.
