Crystal Clear Anti Yellow Metal Stand Case" is a iPhone case designed with the following features:

1. Crystal Clear: The case is transparent, allowing the original design and color of your iPhone to show through.
2. Anti-Yellowing: The material used is specifically formulated to resist yellowing over time, which can happen with some clear plastic cases due to UV exposure and other factors. This helps maintain the clarity of the case.
3. Metal Stand: The case incorporates a built-in metal stand or kickstand. This allows you to prop your iPhone up horizontally or vertically for hands-free viewing of videos, video calls, or browsing.

These types of cases aim to offer a combination of protection, aesthetic appeal by showcasing the iPhone, and added functionality with the stand. The "metal" aspect of the stand suggests durability and a premium feel.
