Excellent prop. I have the perfect bill to egg routine for this prop. You can show it and then
conceal it easily in your hand. Well made and made to last. I will say that it does not squish
down as small as most sponge balls. You can squish it down to about half it's size. That is enough
to conceal a ball in your hand, but you would need to have pretty big hands to conceal more than
two. You could hold make it appear you have a couple balls and produce four, but you probably
couldn't conceal all four.
All in all, top notch and definitively will be of use.
