Every so often someone comes up with a cufflink design that is a little differnt to all the others. These titanium Tube cufflinks by David Parker are the perfect example. Each cufflink is made for a tube of titanium with two circles cut on either side. They are designed so that the four layers of the fench cuff sit in the round cut-outs and all you see on the cuff itself is the top and bottom circle of the tube. A clever and very stylish design.
