Using this wallet is a breeze. You can put your bills in the double currency compartments, slide your credit cards into the four slots, and place your ID in the ID window. The back zip - around pocket is perfect for storing small items like coins or receipts. When it comes to maintenance, use a soft, dry cloth to wipe off any dust or dirt. Avoid getting the wallet wet as it may damage the leather. Keep it away from sharp objects to prevent scratches. And since it has an RFID - blocking lining, you don't have to worry about unauthorized scanning of your cards.
