The Phantom Collection Rubber Silver Tone Cufflinks form a window onto infinite possibilities. Each cufflink face is silver toned with a highly polished finish. Black rubber laid onto the face is diamond cut into six rectangular windowpanes, so that the luster of silver shines through. The bullet back closure secures them to your sleeves. The size of each cufflink is 5/8 by 5/8 inches. These unusual cufflinks hint at the untapped potential of unknown territory.
