These threaded ball ends are made of implant-grade titanium that is polished to a mirror finish and anodized yellow, for the look of gold at a fraction of the cost. Sold individually. For a pair, select a quantity of 2. These ends screw on, and work only with internally threaded barbells of the same gauge. Threaded ends and posts are sold as individual pieces. If you’re looking for a complete piece of jewelry, make sure to purchase a corresponding threaded barbell shaft or post for your end.
