The Jack is an all-around great wallet. A Jack of All Trades, if you will. It can hold cards, cash, business cards, an ID- There's nothing it really can't handle.
It is made of Italian leather from Conceria 800 tannery, and entirely hand stitched. It is recommended to carry around 5 cards plus an ID, but remember that its capacity will increase with age and stretch if you decide to stuff it full.
