This ring takes the effort out of trying to put in a ring and keep it in place as it has a hinged design. It opens and locks into place with a click. It is a simplistic and fun way to showcase your piercing. It is anodized yellow on ASTM F-136 titanium. This piece is sold individually in a 20G-18G and in variety of diameters to fit your piercing comfortably. Titanium is a great piece for anyone with sensitivities!
