If you prefer to keep your cards and cash together in one safe place, then consider going for the Volterman Bifold model; still slim, still lightweight, but can store several cards and cash. Slightly larger than the Cardholder, this model can store more whilst also providing you with a power bank and Wifi connection. Simply arrange your cards and money, pop the Bifold in your pocket and you are good to go. As with all Volterman wallets, this model is impact resistant, RFID protected, waterproof and made from the highest quality of leather. The Bifold has 6 pockets for cards and 2 inner pockets.
