To use this wallet, simply open the bi - fold design. Put your notes in the note pocket and your cards in the card slots. The window can be used to display an ID or other important cards. When you're done, just fold it up and carry it with you. For maintenance, keep it away from sharp objects to avoid scratches on the canvas. You can gently wipe it with a soft, dry cloth if it gets dirty. Don't expose it to extreme heat or moisture, as this could damage the material.
