Make The Jack Of You!   There are endless uses for this deck of (60) blank playing cards from Roylko. The backs are a star-and-dingbat pattern, white on red. The fronts are blanks, waiting for you to create flash cards for classrooms, whole new games of your own, or a custom deck of cards with your very own design. (Make yourself the King of Hearts, or create the six of pickles!) Already achieved Satori? Leave 'em blank and play Zen Solitaire. Standard card size: 3-7/16" x 2-7/16".
