MIKOL is selling marble iPhone covers for the 6 and 6+. Yes, the cases are made out of actual marble, making them among the classiest iPhone covers money can buy. The company also sells marble covers suited for iPads, MacBooks, and regular-ass notebooks. You remember notebooks, right? Those are basically like an analog version of a laptop.
Thanks to Michael for sending in the tip! He has a marble case for all his Apple devices because he fancy. I like your style!
