Dry Case Tablet I Pad Etc 2013. Dry Case Tablet is a flexible, crystal clear waterproof case that allows complete use of your tablet, e-reader or I Pad while keeping it dry and clean. Dry case don’t just claim to be completely waterproof but we demonstrate it with our vacuam seal. The vacuum seal takes all the air out of the case so there is no way that water can enter. There can be no exchange of gas (air) for liquid (water). The vacuum seal also allows full use of your touch screen because it seal flush on the face of the tablet.
