This is the largest case in our Submersible line. Big enough to protect all sorts of valuables at the beach, on the boat, or on the trail. Perfect size for tablet computers. Touch screens on devices will work as normal. The Aquaclip® (a patented, ultra-secure, rustproof, injection-molded plastic seal) opens and closes with a simple twist of two levers, and everything stays in one piece even when open.
