In less than a year, the Denver-based Kicking Mule Workshop conquered the must-have lists of every denim admirer and satorialists alike due to a unparalled quality and clever details. Unfortunately, this year is KMW’s final run, which might elevate every piece of them a true collector’s gem including this limited slim and simple card holder. Cut, fold and sewn entirely by hand somewhere in Japan using age-old fish-oil tanning techniques, which allows this wallet to gain a quite unique patina over the years of use.
