The ridge is a minimalist, rfid-blocking wallet. The main cardholder uses elastic to expand to hold up to 12 ids and credit cards. The typical leather bi-fold gets packed with faded receipts and unnecessary cards, resembling something more like a suitcase rather than a wallet. The ridge is minimalist without being limiting. It’s about carrying less but always having what you need. Cash strap: a thin and versatile elastic. Ideal for carrying: cash, id's, or rfid-enabled cards. Money clip: a traditional money clip made from spring steel. Ideal for cash, rfid-enabled cards, or business cards.
