To use this wallet, simply insert your cards into the card slots and your cash into the cash compartments. You can also put small items like coins or receipts in the zipped compartment. When you're out and about, keep it in your pocket or bag. For maintenance, use a soft, dry cloth to wipe it clean if it gets dirty. Avoid exposing it to sharp objects to prevent scratches. Don't soak it in water as it's a PU material and might get damaged. Keep it away from direct sunlight for long periods to maintain its color.
