This ring takes the fight out of trying to put in a hoop ring as it has a hinged design. It opens and clicks closed. It is a fun way to showcase your piercing. It is anodized purple on ASTM F-136 titanium. Sometimes some blue can show through. This piece is sold individually in a 20G-18G and in variety of diameters to fit your piercing comfortably. Titanium is a nice piece for anyone with sensitivities!
