Live life hands free and worry free with the beautiful Sparkle hipS-sister phone shield. The phone shield offers you protection while still enabling you to use your cell phone as required. Slide your phone in your phone shield and into your hipS-sister for peace of mind. *Research suggests that this material, made up of stainless steel fibers, may protect the wearer from electromagnetic fields caused by cell phones. Wear the green side against your body for maximum protection. The side with regular hipS-sister material is the side that will send and receive signals.
