The brilliant invention of a chap named Max Templeton.
Yes that's right, JUMBO CARDS.
No gaffs, no palming (obvi), no set ups, no trick envelopes, no kidding.
I couldn't believe this when I first discovered it. It seemed too good to be true, so simple so easy, just one simple move (if you can call it that) and four cards travel from one packet to the other. Cards that were counted by the spectators and sealed inside normal un-gaffed envelopes.
Seriously the magician barely touches anything.
Perfect for stand up shows as the cards are kept above the waist at all times and, of course, they're huge!
Consider using postcards for an obvious presentation about travel,
or company flyers...
or flattened table tent cards or...
you'll see, it has a million applications.
