Double Back 2.0 by Jon Allen

Double Back is the strongest, most visual, and most engaging opening card effect ever created.

A pair of 5s and a pair of Kings are shown front and back. You hand someone the 5s while you cleanly show the Kings. Instantly, you now hold the 5s while your helper now holds the Kings!

Double Back is established as a modern-day classic amongst 'packet effects'. There are a number of variations to Dr Daley's Last Trick, but this is the perfect version. Simple to perform, clean, direct with a stunning visual change. This is magic at its absolute best. Resets automatically making it perfect for walk around or table magic.

Comes with necessary cards, gimmick and online tutorial with step-by-step instructions, handling tips, presentational advice and subtleties honed over thousands of performances.

"The best reactions I've received from any packet trick." - Jon Armstrong

"I've performed Double Back for years, and it always gets killer reactions." - Chad Long
