Cardholder Planas from Saddler. A sophisticated cardholder made of super-smooth, soft and sleek leather, lined with exclusive goat leather. Planas is our slimmest cardholder with a minimalistic design that still offers five card slots. The RFID lining at the front of the cardholder (where the logo is) shields your cards from skimming. The back of the cardholder offers storage for, for example, bus or gym cards that can be used without being removed.
