Clear, undistorted reflection: The front surface is made of glass with a PS (polystyrene) backing, providing a smooth, frameless mirror face for true-to-life, distortion-free viewing. Strong magnetic attachment: A powerful magnetic backing lets the mirror mount securely to any flat metal exterior (locker doors, metal cabinets, etc.). It holds in place during daily use and reduces the risk of falls or breakage. Safe, user-friendly design: Rounded corners and smoothly polished edges make the mirror safe to handle and reduce the chance of cuts. Each mirror comes with a protective film that should be peeled off before first use. Durable materials and simple maintenance: Glass front and PS components deliver a balance of clarity and light weight. Wipe clean with a soft cloth; remove the protective coating before cleaning the mirror surface. Practical and versatile: Ideal for students, schools, athletes, and travelers. Use it as a practical tool for quick checks or as a makeup mirror. Use scenarios 1) School locker: Attach to the inside or outside of a metal locker door for quick grooming or appearance checks between classes. 2) Gym or sports locker room: Mount on the locker door for pre- and post-workout touch-ups or equipment checks. 3) Travel and dorms: Stick to metal cabinets or dorm-room lockers for a compact, reliable mirror without drilling or adhesive.
