Is it luck or fate? The answer is in your hands with BDM Safe Box.
This effect starts by placing a bet or prize inside a metal box and locking it. The correct key is then mixed in with 4 identical other keys. A variety of spectators are then allowed to freely select any key, leaving the last one for you. They can even exchange the keys if they don't like their decision.
Everything happens in full view. Yet, without any sleight of hand or key switches, you're always left with the only key that opens the box.
This is just one of the many amazing routines that is possible with the BDM Safe Box. Here's the best part, they're all incredibly easy to do!.
