Threadless Bent Barbells - With their simple snap-in ends, our threadless bent barbells are a convenient alternative to threaded jewelry. Simply put the curved barbell through your piercing, push the end in, and it snaps right into place! When you want to take your curved barbell jewelry out, the end will pop back out easily. Choose from threadless bent barbells with balls or cones/spikes and in the ideal length and gauge for your piercing. (Patented design.)
