The Cudworth Gold and Navy Silk Knot Cufflinks Set pairs the warmth of gold-toned silk with dependable navy, giving you both a quiet everyday option and a dressier one in a single box. Each pair is formed from two woven artificial silk knots joined by a flexible cord, so the colour is in the silk itself with nothing plated to tarnish and nothing rigid to press on the wrist. Navy suits daily business wear while gold lifts white and cream shirting at an event. Materials: Artificial silk.
