The Ögon cardholder holds up to 10 cards, depending on how much cash you keep in it. Ögon Designs cardholders also provide protection against data chip reading found on the cards. This is ensured by the aluminum shell. The Ögon card case was designed in Sweden by a team of designers and is inspired by the style of suitcases from Zero Halliburton and Rimowa. The black Ögon credit card case is made from high-quality aluminum and very durable plastic.
