Krown is an indie iPhone case manufacturer that offers cases for Apple's newer devices, including the iPhone X, iPhone 8 and 8 Plus, iPhone 7 and 7 Plus, and the iPhone 6s and 6s Plus. The company makes cases in four materials (prices for iPhone X): aluminum ($24.95), concrete ($39.95), an ultra thin plastic ($19.95), and marble ($49.95). All Krown cases with the exception of the aluminum model are compatible with wireless charging.
The Slim Aluminum Case is made from a brushed aluminum material that comes in blue, black, gold, or red. To protect the iPhone, there's a soft rubber material inside of the case, and it features a lightweight, minimal design with no unnecessary bulk.
Krown's Concrete iPhone Case is thicker than the aluminum case, but as far as cases go, it's still relatively slim. It's made from a concrete and resin material that's smooth to the touch, and inside, there's a soft rubber for drop protection. There are two shades of concrete available: dark with a black border and light with a white border.
The Ultra Thin iPhone Case is similar to other ultra thin cases on the market, measuring in at 0.012" thick. These kinds of cases often don't offer much in the way of drop protection, but they're the best way to preserve the slim design of the iPhone while also protecting it from scratches. Krown says its version, available in dark blue, black, red, and white, is designed to "feel invisible."
Krown's Marble iPhone Case is similar in design to the Concrete case, but instead of a concrete back, the outside of the cases is made from a thin layer of genuine marble that comes in black or white. Inside, there's the same soft rubber used in other cases, which offers protection for drops and bumps.
