I have to admit I am on the fence as well. The reason why I like it is because the effect is as seen
in the video and you just can't argue with that. You can bring this envelope to a party and leave
your playing-cards at home, because you don't need them. Thats's another thing I like, the method.
Fantastic (they truly always tear up the cards they want to tear up). What I don't like is that the
envelope will maybe last some time, but it will obviously not look like new after a while. There
will be tiny creases, it'll get dirty, and so on. They acknowledge the problem in the instructions,
but that doesn't help ME. I still recommend to buy this, overall. If you are a pro it will be worth
to buy another envelope from time to time. And if you are not, your envelope should surely last 30
to 40 performances and still look tolerable. Enough for mum, Dad and the dog. There is one more item
you should get from an office-supply store, it is mentioned in the instructions. The makers sell the
envelopes, but they are so expensive you hardly save $ compared with penguin. I think they should
drop the price for people who purchased the effect. Good trick with flaws. If you can track down the
envelopes (brand-name mentioned in the instructions) and if it's possible to make them yourself, pse
post at Penguin-only section. Thanks.
