My backed bracelets are the result of many iterations of what would otherwise be a simple design. Half inch tree spikes are sandwiched between two layers of Wickett and Craig Harness leather. The Oxblood backing prevents the backs of the spikes from irritating your skin. The strap of the bracelet - the most stressed area - is stitched along the perimeter for reinforcement. This bracelet will continue to keep you looking very sick for a very long time.
