Using this wallet is super easy. Just unzip it and you can slide your cards into the 5 slots provided. Keep your most important cards like your ID, credit cards, and membership cards here. When you're done, zip it up securely. As for care, avoid getting it wet as the vegan leather might get damaged. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. Store it in a cool, dry place when you're not using it. And since it's an officially licensed DC product, show it off with pride and let your love for Batman shine!
