Black
Clean, direct, permanent. The brass hardware sits warmer against it than expected. It doesn't announce itself.
For dogs of people with standards.
Full grain leather doesn't wear out, it wears in. The more it's used, the richer it becomes. Softening where it bends, darkening where it's touched. A year from now it won't look new. It'll look like yours.
Each color with its own logic
Cognac
The color the leather wants to be. It deepens at the edges over time, softens where it bends, darkens where it's held. A year from now it won't look new.
