4.0 out of 5 stars Works incredibly well, even on security envelopes.

This stuff is really great. It works like a charm even on security envelopes. The only thing is that you don't have much time...once you spray the envelope you have about three seconds before you have to respray it to make the paper transparent again. The good thing though is that no matter how many times you spray the paper, it never leaves a trace.

5.0 out of 5 stars Really works!

I was extremely skeptical about this spray before I bought it thinking it was too good to be true.

I was impressed with how well it actually works. It makes the envelope transparent for about 20 seconds. It does work a little better on white than yellow, and I also saw better results when the envelope was pressed firmly against the contents.

After about 20 seconds, the envelope returns to its original opacity, and you can't even tell that this had been sprayed on!

3.0 out of 5 stars DO NOT GET ON HAND
Reviewed in the United States on March 12, 2013
Works great on paper, sprayed a little on my hand and now I can't see it!
I closed it in a door and cut it chopping onions. Says it's supposed to wear off but my hand has been invisible for 4 DAYS.
Temporarily spraypainted hand black in order to see, which makes it sticky and leaves black marks on clothing.
Please post solution.

I was impressed with the product. Tested in several different envelopes, and all worked. The envelope is virtually transparent, and soon after back to normal, not getting stains or smells. The contents of the envelope is also not stained papers tested with various types of printing (inkjet, laser, etc.) and there was no problem.
Recommend to everyone!

This stuff is too cool. I wish the coolest things weren't illegal. :-D
Anyway, it's a neat trick, even if you aren't breaking the law while using it.
