Case-Mate has partnered with the Common Ground Foundation to create these dynamic cases inspired by urban street art. Show your support for this wonderful organization - dedicated to providing inner city youth with new opportunities through the creative arts - with the Case-Mate Galaxy S III Common Ground Tough Case. The Tough Case is comprised of a hard polycarbonate exterior and a silicone interior skin. These two layers work together to protect your phone from dirt, scratches, and everyday wear and tear. With custom cutouts for all ports, buttons, and the camera, your Samsung Galaxy S III will remain fully functional while in the case.
