The iPhone 14 Pro Max Clear Case with MagSafe is “Crafted with a blend of optically clear polycarbonate and flexible materials, the case fits right over the buttons for easy use. On the surface, a scratch-resistant coating has been applied to both the interior and exterior. And all materials and coatings are optimized to prevent yellowing over time.”
The sides of the case use a more flexible, rubber-like material to allow for a better grip, while the back of the case is more rigid.
The case also includes MagSafe magnets that extend the functionality of MagSafe built into the iPhone through the case. Apple described the functionality: “With built-in magnets that align perfectly with iPhone 14 Pro Max, this case offers a magical attach experience and faster wireless charging, every time. When it’s time to charge, just leave the case on your iPhone and snap on your MagSafe charger, or set it on your Qi-certified charger.”
I have used Apple’s clear cases since the iPhone X. As Apple indicates, the cases have not yellowed significantly over time.
