Shell cordovan is a leather apart: it comes from the fibrous membrane beneath the hair of draught horses, worked for six months by the tanneries of Chicago (Horween) or Hyogo (Shinki Hikone). It does not grain, it does not crease, and it develops over time a depth of patina that no other leather matches. Alongside the shell we keep Japanese cordovan, French chèvre, lamb and elk — leathers that are difficult to source, each with its own singularity.
