The Rokform TPE non-slip grip keeps your phone from sliding across slick surfaces but doesn't get caught up in your pocket. These come solid backed for non-magnetic use. About Rokform is an ordinary group of people with an extraordinary passion for creative and functional technology accessories. We aim to improve lifestyles through developing unique and protective cases, mounts, stands and accessories. We love what we do, love how we do it, and want to share that love with the world. You won't catch a Rokform team member who doesn't have multiple places to mount an iPhone, iPad or Galaxy S3 around the house, office or car (most of us are addicted to the Lil'Rok)! Oh, we also love WHERE we do what we do. Nearly everything from concept to completion is done in Santa Ana, California, and allows us to maintain utmost control over quality and timing. Yep, that's right, made in the USA. Since Rokform was founded by veterans of the power sports industry, we get to draw on their expertise of high tech materials and manufacturing methods which you'd normally find in aircraft and high performance racing vehicles. These methods and materials make up the really cool, award winning phone cases and accessories you see today.
