Saddle stitching is a rugged hand sewing technique that cannot be reproduced by sewing machines. All our products are made accordingly.
It takes forever to stitch, aches both hands, can't mass produce but our wallets don't ever break (unless a polar bear chews on it).
Fun fact: The earliest instance of saddle stitching dates back 365 AD. Saddles had to be tough and capable of enduring a lifetime of hard labor under the sun, wind, rain and snow. To this day leather saddles are still hand-sewn.
