Review
From the site -"The Working Performer’s Sensor Envelope is a real miracle. We are all in search of miracles and if a spectator could write a message on the back of his visiting card seal it up in an envelope and in less than ten seconds you could know exactly what was written inside the envelope – that would be a miracle. And that is exactly what you can do with The Working Performers Sensor Envelope.
Nothing is added, nothing is taken away. No other props are required. This envelope uses a new principle never ever used in this way before. You will be truly astounded when you receive this effect. It has taken nearly a year of research, trial and error to achieve. I have discussed this principle in confidence with leading mentalists and not one of them had heard of this before. You will not find it mentioned or even hinted at in any book or magazine on magic.
Andy Nyman said, ‘This has a million possible uses and all deadly – Fantastic.’
When you receive the envelope I guarantee that you will play around with it for hours and you will wonder at the way in which it does everything for you. Now you can perform sealed message reading acts without using ***-***** methods. Almost as soon as you pick up the envelope you know what is written inside. No sleight of hand or flaps or cuts or slits. It is just one piece of paper made into an envelope. A number of top mentalists have received early prototypes and I am certain they will be contributing routines as we go along."
Overall
This is actually a little hard to review without tipping the secret, but here goes….You get 3 envelopes to start with, I use a tiny dab of changing glue along the lip of it for sealing purposes. You can place a piece of paper with any info on it, hold the envelope in plain sight yet still be able to decipher what was written easily. No gaffs, no extras at all. 3 simple envelopes….a very james bond kinda thinking has been applied…no extra hidden parts or electronics either. Its down to you how you reveal it as with any billet work, but there are seriously no special moves at all…it’s a unique method definitely….i've used it at a dinner party fairly recently with people all around me too - revealing names of loved ones via spirit-writing on napkins was alot fun….
For me, a charming 9.5 out of 10…
