Compatible with devices 2.4 to 3.5' wide, the ST-30 Phone Clip y Mirror Kit from Ulanzi features a clamp that securely holds your mobile device in place, as well as an integrated mirror with a 360° rotation. When used together, users will be able to take better selfies using either the front or rear cameras of their mobile device. A female 1/4'-20 thread on the bottom lets the ST-30 be attached to a tripod, while a cold shoe on the top lets users mount a light, mic, or other accessories. A protective pad helps ensure the back of your phone won't get scratched, while a nonslip pad within the grip helps keep a firmer hold on your device.
