The functional case design for iPhone. With our smart design, we created a functional accessory case for Apple iPhone. Just simply lift the D-ring off and place it into correct position. 1. As kickstand: place it into 90 degree, D-ring becomes kickstand for watching movie or internet. 2. As headset storage: place it into 180 degree, D-ring becomes a perfect storage for headset. Roll up the cable around the bottom of the D-ring, and pass through the headset and secure it. 3. As neck strap: in 180 degree position, with our extra neck strap, users can hang iPhone on their chest.
