I feel like i got punked when looking at these. First thing when spreading through them I noticed
the Window envelopes. 1 of them has glue and a scratch on the window - unusable. The next one had
glue around the window -ahhh unusable. I don't have much experience with gaff envelopes which is
part of the reason for picking this set up - to learn more about them. There is nothing to learn
here, no teachings or ideas. Now, it does not say that it comes with any of that. I poorly assumed
that there would be 'something'. I have gotten a dual out envelope with an effect one time and it
was great. Which is why i got interested in this product. You could open the envelope and have the
spec take out the card (or billet) and there was nothing for them to see or even think something was
up. You cannot do that with these. Its very blatant. In fact, you have to turn the envelope away
from them as YOU take out the card/billet - that ruins the effect when you are obviously hiding
something.
I don't have any problems with the majority of your review.
However, I have to debate your conclusion.
You said "...you have to turn the envelope away as YOU take out the billet...that ruins the effect when you are obviously hiding something."
It only ruins things if you can't provide the proper misdirection.
The spec will only think something is fishy if you give them a reason to think that, so don't give em the reason.
So unless these envelopes have a bright red arrow pointing at the gaff, you really shouldn't have any issues with what you said there at the end.
Sincerely, there are far worse things in a billet switching routine to worry about.
