Using this card holder is super easy. Just open it up and slide your Ultra Replica Ultra Fusion cards into the slots one by one. You can also place it on the display pedestal to show off your cards. When it comes to maintenance, keep it away from sharp objects to avoid scratches. Also, don't expose it to extreme heat or moisture. If it gets dirty, you can gently wipe it with a soft, dry cloth. That's all you need to know to make the most of your card holder!
