This is a slim design bifold wallet with a stunning exterior leather. Shell cordovan is an exotic leather made from a horse rump and is typically used in luxury shoes. This particular leather is by Rocado, with a museum finish (blotchy dye job). It polishes up beautifully and feels amazing in the hand. 
The interior is chocolate kangaroo leather, with four card slots and space for notes or extra cards behind. Having the cards in this orientation means they can’t fall out of the wallet is folded in your pocket. 
Kangaroo leather is the strongest leather for its thickness, and will last many years. Hand stitched with white thread in a traditional saddle stitch, and finished with a glossy edge burnish that will last.
