The PolarPro CrystalSky 5.5 inch Screen Cover was developed to protect the larger CrystalSky screen while traveling or anytime the monitor is not in use. Each Screen Cover is made from a durable injection molded rubber, strong enough to provide adequate protection yet soft enough to not scratch or scuff the CrystalSky screen. The Crystal Sky Screen Cover is engineered to securely snap onto the monitor and will stay put on your toughest adventures. The inside surface of the screen cover is a soft textured rubber to ensure your screen is safe from scratches or marks. The Screen Cover is backed by PolarPro’s lifetime warranty and backed by U.S. based customer support.
