To use these playing cards, simply open the full - color cardboard box. Shuffle the 52 - card deck well before starting a Poker game or any other card game you like. When handling the cards, make sure your hands are clean to avoid soiling them. After use, put the cards back in the box to keep them organized. Store the box in a cool, dry place to prevent the cards from warping or getting damaged. Don't bend or fold the cards roughly, as this can affect their durability and usability.
