To use this wallet, simply slide your cards into the 8 card slots and place your notes in the note pocket. You can also use the 2 additional compartments to keep other small items like receipts or coins. When it comes to maintenance, use a soft, dry cloth to wipe it clean regularly. Avoid getting it wet as much as possible. If it gets dirty, you can use a mild leather cleaner. Store it in a cool, dry place when not in use to keep it in good condition.
