The Lone Wolf Leather Card Wallet packs at least four cards and is a great option when what you need to cary needs to be less bulky. When traveling it's great as an extra wallet for your most needed credit cards and your hotel key. This card wallet is made of Shinki Hikaku's world renown shell cordovan leather also known as horse butt. Shell cordovan is made up of very small and tight fibers and therefore ages with grace. Unlike leather from other animals small scratches will "self polish" with use. The card wallet is hand sewn using French Fil au Chinois "Lin Cable" waxed linen thread.
