The DESTROYER for Apple iPad 1 utilizes reinforced side rails that are held in place by screws to ensure a snug and durable fit. Installation is a breeze with the included allen wrench. The high-impact resistant, glass-reinforced nylon outer shell is complimented by a soft and shock-absorbing silicone core - an innovative combination that provides unmatched protection. The DESTROYER comes with two included screen protectors - Anti-Glare and Clear which allow you to prepare your iPad 1 for any environment you take it to. Cut the glare or have a crystal clear screen - use either one - but ensure the safety of your touch screen.
