Phone straps have become a popular way to not only carry a phone, but also to help prevent dropping or misplacing it. The patch fits between the phone and a phone case, with a loop popping out of the charger port opening of the case. The loop can then be attached to the clip of the adjustable cord. By adjusting the length of the cord, you can choose to wear it as a crossbody strap, a shoulder strap or a neck strap.
