Double Back Red Blue Bicycle Playing Cards

This is a great trick and easy to do, one side of the deck is all red the other is blue, just pull them out of the box, show the audience one side, carefully not revealing the otherside, place them in the box, wave your hands over it and when opening it back up flip the box upside down so when you pull the cards out you will show them the other side. The is very cool trick and can be done in other variations, just use your imagination and have fun with this. This is for 1 complete deck 56 cards, one side of cards are blue the other is red, box color varies and is randomly picked for you. The deck is new never used but none of them have seals on them.
