To use this wallet, simply open it up and insert your cards into the card slots, cash into the note pockets, and coins into the change pocket. The stud fastener on the change pocket keeps your coins secure. When you're not using it, you can easily slip it into your pocket or bag. To keep it in good condition, avoid getting it wet. If it gets dirty, you can gently wipe it with a soft, dry cloth. Don't use harsh chemicals or abrasive materials on it as this may damage the PU material.
