Thirty years of research from Harry Robson has led to the exact formula of what we now present: the Roughing Stick. This is a stick of a hard substance and what it does is simply incredible.
When you rub the surface of the stick against a card, it will act as roughing fluid does, only better. The cards stay together in roughed pairs, yet are more easily separated without fumbling whenever you want. The stick leaves NO RESIDUE, and with the roughing stick supplied you can create at least 150 Invisible Decks! This is, for all purposes, a LIFETIME supply. The best part? It's so inexpensive.
Imagine the possibilities Packet tricks, Brainwave, Invisible Deck, and more just got MUCH easier to make, on your own, and many original tricks that would have required a spraying shed or a craftsman to manufacture can now be done at your kitchen table within minutes.
Note: This is the same product that I use to prepare my Comedy Bill To Lemon Deck & The Slot Machine Deck. I keep one in my close up case and one in my stand up case!
