The Cudworth Blue Silk Knot Cufflinks Set brings together coordinating blue silk knots, giving you several ways to finish a cuff from one purchase. Each pair is built from two woven artificial silk knots joined by a flexible cord, light on the wrist and free of the hard fittings that make metal links uncomfortable under a desk. Blue is the easiest colour to wear with navy, grey and tan, which makes this set a sensible starting point or a straightforward gift. Materials: Artificial silk.
