Thanks to its black edge-printing, the Black and White edition has a classy stealth look that feels like it's been made of materials from another planet. Classy Black-printed edges! A black edge is a beautiful edge. But it's well known that black edge-printing interferes with how cards feel and the smoothness of fanning. With the help of Cartamundi, we are working with edge-printing specialists in France whose work not only protects the quality of the cards, but enhances the pack's magical features, and defends against humidity and hand moisture that so often weakens un-edge-printed cards along their vulnerable edges. The marked edition contains 54 cards, a double-backer, and an instructional card which explains the marking systems. All Butterfly Playing Cards Black decks are printed by Cartamundi on Slimline card stock with the True Linen B9 finish. What is the difference between the marked and unmarked cards? The marked Butterfly deck will empower you to perform miracles not possible with any other deck of cards in the world. So if this is your goal, go for marked.
