Made of a combination of optically transparent polycarbonate and flexible materials, the case fits within the buttons for ease of use. Scratch-resistant coating has been applied to the inner and outer surface. All materials and coatings have been improved to prevent yellowing over time. With built-in magnets that perfectly match with iPhone 13, this case provides a magical attaching experience and faster wireless charging every time. When it's time to charge, leave the case on the iPhone and use a MagSafe charger, or place it on a certified Qi charger.
