One of the effects you can do is this:
You have any card chosen and signed and returned to deck.
You shuffle the deck.
Then you point out a small box on the table that's been in sight the whole time.
You open it and inside is a tic-tac box with a folded card in it.
You slowly pick up the tic-tac box remove the lid and tip out the folded card into the spectators hand.
They unfold the card to reveal their signed selection and everything can be inspected.
I've got this DVD and I personally must recommend it.
its so simple yet it is the simplicity that dumbfounds every person I show it.
Also if you've a PK ring then it can be performed 100% clean, you can start performing as soon as you know the method.
If you wanted to, a bit of practice is always advised. LOL.
