Designed for harsh environment use, this tablet cover is made from polyester and features easy to adjust velcro closures. To open, access, or remove the tablet if it needs maintenance or recharging, simply peel open the Velcro closures. The clear rolla glass vinyl screen lets you see the screen and have access to full touch screen functionality. If the screen gets dirty, simply wipe it down with a soft cloth and gentle cleaner or replace it with a new screen.
