If you do any mentalism work, this is a prop that you really need to have. Given the low price of
this one, it's as good a choice as any. It's sturdy enough to hold up for a while, so you'll
definitely get your money's worth.
What you won't get are any creative suggestions for what
to do with it. Personally, I wouldn't use it for selecting a playing card as shown in the demo,
because that's just a really odd way to get someone to select a card, and it automatically makes
your bag look suspicious. Instead, use it for something in which it makes sense to use a bag for
holding and mixing up a bunch of items. Refer to anything by Osterlind if you want to see some
excellent effects using a force bag.
