With the OtterBox Commuter Series case offers three layers of protection. Layer one consists of a self-adhering screen protector that prevents any scratches or blemishes from ruining the view. The second layer is a soft silicone wrap that helps any avid reader grip the device while also absorbing shock from accidental dings or drops. Cases for Kindle 3 and Kindle DX include a fully interactive keyboard cover to keep the keys in pristine condition. Additionally, silicone plugs protect the ports for all devices in order to keep out dust or dirt. Lastly, a polycarbonate shell snugly fits around the silicone, making it easy to slip in and out of any book bag or briefcase.
