Vintage 80s, Men's SWANK cuff links. Silver/silver

Vintage early 1980s cuff links by SWANK, stamped on reverse. Cross hatch silver tone on smooth silver tone pair. Decorative part is non-magnetic, so that part could be silver/plated. The bar on inside that goes thru the buttonhole is magnetic. Excellent condition. I can't find the tie-tack that came in that box. Box comes with cuff links. Non-smoking home.
