To use this wallet, simply insert your cards into the card slots and your notes into the note pockets. For IDs, put them in the window slot. Coins can be stored in the change pocket and secured with the stud fastener. You can use the two extra compartments for small items like receipts. When it comes to maintenance, use a soft, dry cloth to wipe it clean. Avoid exposing it to excessive heat or moisture as this can damage the PU material. Also, don't overstuff the wallet to prevent it from losing its shape.
