Superblack Pen Black Rhodium Solutions

Cohler Superblack Pen Rhodium produces a deeper, darker grey-black rhodium plate on gold and other precious metals than standard black pen rhodium. Formulated specifically for pen plating, it uses a different pH and higher concentration than bath rhodium solutions to deliver crisp two-tone accents, touch-up repairs, and uniform dark finishes. For professional use only.
