This highly flexible and waterproof sleeve protects your cell phone from water damage. The front of the sleeve is made from transparent silicone film and is fully compatible with your cell phone?s touchscreen. A smaller silicone film window on the back allows you to use your rear-facing camera in the water. Have fun taking photos while you surf and swim! A special dual snap-closure device seals the sleeve to prevent leaks. The case can be comfortably worn around your wrist or ankle with the included velcro strap. And you can also attach the case to your keys or clothing with the included lanyard leash.
