At AMiGAZ, we make most of our wallet chains ourselves. We start with a quality piece of chain (various lengths) and then add our hardware. On one end you have our Sturdy Snap Hook to attach to your belt loop. It has a swivel base that will keep your chain lying flat instead of twisting. On the other end we add two more pieces of hardware. One is a bull-nose clasp to clip-on to your wallet (or anything else). The other is a twist-off D-Ring which can be placed anywhere on or off the chain, and is great for keys, bottle-openers, or AMiGAZ Clip-on's!
