Or licensing a completely homemade way , good idea!
Duplex is a card rising effect from the mind of Kevin Schaller that you are definitely going to love!
A freely chosen and signed card is lost into the deck and the deck is put back into the box. Without any funny moves the signed card starts to rise all the way out of the box.
The best part of the trick is that there are no threads, wires, weights, rubber bands or magnets -… Just the box and the deck No forcing No cellophane needed Box can be shown empty and from all sides – front and back. Automatic reset Note:! Requires Bicycle Cards!
