Using this wallet is super easy. Just unzip it to access your cards and cash. You can put your regular cards in the four slots and your ID in the clear holder. When you're done, zip it up to keep everything secure. As for maintenance, use a soft, dry cloth to wipe it clean if it gets dirty. Avoid getting it wet for a long time as it's made of vegan leather which might be affected. And since it's an officially licensed product, take good care of it to enjoy its cool design for a long time.
