The Cudworth Navy and White Silk Knot Cufflinks combine one navy knot and one white knot for a nautical, easy to wear contrast. Each cufflink is made from two woven artificial silk knots joined by a flexible cord, giving a soft, lightweight fastening with no metal fittings to catch on a sleeve. Navy and white is the most useful two-tone combination in the range, sitting comfortably with navy blazers, grey suits and open collar summer shirting alike. Materials: Artificial silk.
