This is the stainless steel pendant shank that goes with all of my interchangeable ringtop beads. It is appr. 48 mm long and has a stainless steel screw and body. Screw your favorite threaded top on and you have your beautiful pendant. The screw is compatible with the changeable systems such as Ring Ding and Sunset Blvd and other 2.5mm threaded systems found in Europe and abroad.
