From our Daniel Smart Collection... 

Our Smooth Leash Hack Wallet Chain is a solid, weighty chain that we've "hacked up" with our Knight Hack Plating. Dark, rough, distressed. Similar to a leash chain, but the links are smooth instead of filed. This is a heavy chain, 100% made in the USA, with superior quality and styling.

Steel chain, plated with our darker, distressed, Knight Hack, antique finish 

Our hardware (sturdy snap hook and dual wallet hook end-pieces) adds approximately 3" to the listed length of each Wallet Chain 

Chain links measure 3/4" L by 1/2" W, wire thickness approx. 4mm
