To use this wallet, simply open the stud fastener. You can put your credit and debit cards in the 3 card slots, and use the window compartment for your ID. The 2 note compartments are great for holding your cash, and the additional compartment can be used for receipts or small items. When it comes to maintenance, keep it away from sharp objects to avoid scratches. Wipe it gently with a soft, dry cloth regularly to keep it looking its best. Also, don't expose it to extreme heat or moisture, as this can damage the leather and the RFID technology.
