Christopher Simpson's Ballcuffs are an innovative, colourful, fun solution to the problem of cufflinks for everyday wear. Ballcuffs are the new elastic knot cufflink but superior in quality and design. They come in 12 great colours to match a shirt or tie and are easy to put on as they just push through a shirt cuff. Made from silver-plated brass and nylon, each pair is packaged in a round wood-effect branded box (as pictured). The ball diameter is 10mm with 12mm joining bar.
