South Korean design team POSH-PROJECTS continues to impress with their arts and crafts type goods. Their latest is the Luna Concrete Skin ($30 USD) for iPhone 6, a unique protector made out of concrete to resemble the cratered surface of the moon. The texture of the concrete acts as a nice grip alongside its rugged protective design. If the rough exterior isn’t for you, the brand also made a “non-crater” edition offering a smoother version in the same material.
