Circular Barbell – also known as Horseshoe Barbell
The circular barbell is similar in shape to the captive bead ring, except that it is not a complete circle. The ends are screw-on balls (remember, righty-tighty, lefty-loosey). Like barbells and curved barbells, these come internally or externally threaded. As with the CBR, the measurement needed for ordering these is the interior diameter.
Like the CBR, circular barbells come in a variety of materials and can be worn in virtually any piercing. Differently colored or shaped ends are also available for purchase to customize the circular barbell.
