Customised playing cards are the ideal manner to give your campaign a personal approach - this means you have more chances to turn it into a success. You decide the shape and what will be printed on them. You can emphasize the impact by adding special effects such as phosphorescence or thermo-sensitivity. And the message will be in the eye of the consumer during the entire game. Plus, don't forget that cards games are played in groups, therefore, the audience will never be limited to the one that receives the cards deck. Message cards can be combined in a complete deck of cards.
