Magic Tricks

I bought this incredibly expensive set of decks to use it with regular decks and make a kind of riffle force, being the plastic thicker than paper it should do the work. i have used prestige decks ( which have much better quality ) and worked but you can't show the back design wich is trickier... BUT this doesn't work as well as the prestige decks
Also It doesn't spread well so you only can use it like for springs or throws...
And finally i bought two and expected one of each color as penguin people say it could be done before hand, and then they didn't let me cancel my order when they stated that they only have red backs and send it after my multiple complaints!
