These guys are super versatile with a wide range of gauge sizes and colors, including black and rainbow. And with externally-threaded balls on both ends, they are easy to put on and remove all by yourself. They are great for cartilage piercings, septum piercings, and even earlobes! Since they are titanium anodized instead of painted the color won't flake or chip off and irritate your piercing so they are fantastic for everyday wear.
