Compatible with Quad Lock MAG cases, the Quad Lock MAG phone ring/stand and bottle opener offers a more secure grip on your phone with a large ring, a stand for hands-free viewing, or can be removed from the phone to open a bottle. The magnetic attachment allows for 360-degree rotation so you can use the ring at any angle. Simply place the Phone Ring/stand and bottle opener on the back of the Quad Lock MAG case and let the magnets do the rest.
