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 and this may well be the perfect version. It is clean, simple and one of the most visual card tricks ever created.
 
This is magic at its very best. It resets automatically making it perfect for walk around or table magic. Comes with necessary cards, gimmick and DVD with step by step instructions, handling tips, presentational advice and subtleties.
 
 
"Double Back is my favourite packet trick of all time."
