This pendant measures 1.5 inches in length and is made from platinum or gold-plated steel. It comes on a sterling silver or gold-plated chain, in your choice of a 16 inch or 18 inch length. Choose 16 inches for a short, layering-style necklace, or 18 inches for a standard-length necklace. [As a note, we asked an ultra-marathoner friend to try it out for us... She reported it to be both sturdy and so comfortable she forgot she was wearing it.] All U.S. orders come in a beautiful hand-stamped gift box. International orders come in a black velvet drawstring bag.
