The gold plated round 17mm diametere cufflinks feature a katherine wheel design which catches the light as the cufflinks move. The design is repeated in the 10mm tie pin and chain.  These are a versatile cufflink in that the mesh wrap, which is usually permanently attached to the face of the cufflink, is able to be easily detatched. So, you can wear these as either mesh wrap or without the wrap like regular swivel toggel cufflinks. Mesh wrap cufflinks were very popular in the 1960's and 70's and are characteristically bold and showy.  Coupled with the tie pin this set makes a very dapper, vintage impression.    The width of the chain mesh chain is 17mm and the length of the mesh is 50mm. For a double cuff shirt the bottom of  the cufflink hole in the shirt needs to be no more that 25mm from the edge of the cuff so that the mesh can wrap under the cuff and around to be fixed at the back and held in place by the toggle.
