To use this wallet, simply insert your cards into the card slots, place your notes in the note pockets, and drop your coins into the change pocket. The window slot is great for keeping your ID visible. When it comes to maintenance, wipe it with a soft, dry cloth regularly to keep it looking clean. Avoid exposing it to extreme heat or moisture, as this could damage the PU material. If it gets dirty, you can use a mild leather cleaner, but make sure to test it on a small, hidden area first. With proper care, this wallet will serve you well for a long time.
