The leather I use for the Wrist Bands is vegetable tanned Pueblo. It's high-quality leather from a world famous Italian tannery called Badalassi Carlo. Its most recognizable feature is the texture on the surface which they make with a special tool of their own. The surface is matte but the oils used in the dying process make the leather smooth and shiny over time - that's patina. The leather is from a shoulder of a cow so it's thick and strong although the shoulder being near the neck makes the leather a bit flexible. It's dyed through so both sides and inside of the leather is the color cognac.
At Badalassi Carlo they master the art of creating beautiful leather and they work on every skin carefully to maintain their high-quality standards. That's why their leather is widely spread around the world.
