The Synergy Collection Rubber Inset & Stainless Steel Cufflinks are sleek and resilient, muscling their way through the challenges of the concrete jungle. Three smooth ridges of black rubber are framed by a square of gleaming stainless steel. Throughout this collection, the contrast of implacable steel with resilient rubber combines to striking effect. Each cufflink measures 9/16 by 9/16 inches, and uses a bullet back closure. Strong, cushioned and resilient, these cufflinks will turn heads, hinting at your latent power and drive.
