These cards are given a new life in these mini notebooks. Perfect for keeping score on game night, purses, pockets, backpacks, and every time you want to jot something down! Each mini journal is filled with between 30-35 sheets of blank paper and the front and back are 2 separate and different cards. There's no guarantee that they will add up to 21, but it's fun to order a bunch for a party and you can play a game with the journals! This journal is bound by hand on the side with a metal binding and measures approximately 3" x 2.5". Special Notes: The product you receive will be the color(s) you ordered, but may not be the exact card you see in the picture.
