Using this card holder is super easy. Just unzip the pocket to put in your small items like coins or receipts. Slide your cards into the 4 slots provided. When it comes to maintenance, keep it away from sharp objects to avoid scratches on the vegan leather. Wipe it gently with a soft cloth if it gets dirty. Don't expose it to extreme heat or moisture as it might damage the hardware or the lining. Since it's an official Disney product, take good care of it to enjoy it for a long time.
