Our leather products weren't made to be babied. They were made to be used. They'll get marked, they'll pick up the shape of your routine, they'll develop a patina that's yours alone.
That's not wear. That's what real leather does.
If something spills on them, wipe them with a dry cloth and let them air dry — away from the sun. Avoid soap, ink, and alcohol. That's it. The rest takes care of itself.
