I recommend getting the jumbo size. This is a great effect. I always search for practical angle proof, portable Magic Props. This does it all. The only thing you need to add is showmanship and a good story.
One way to make the routine fun is to involve your audience. Kids and adults like this. It can be done close-up or on stage. Highly recommended. You will have people asking you for the secret.
A true Magician does not tell the secret. Remember.
