The Thought transmitter Pro is unique because it does virtually what no other "Peek" wallet in the world doesA spectator writes down a word, a card, or draws something on the back of his business card. The card is then placed between two opaque cards in an opaque wallet . There is no way to see inside of the wallet. In fact if you wanted to, you could put rubber bands around the wallet, and drop it in a clear zip lock bag to prevent manipulation. Wallet can be freely handled. Now without opening the wallet, the magician is able to divine the instant, the written thought at any time desiredWith the new Thought Transmitter Pro you are able to carry credit cards, drivers license, money etc inside the wallet, and you can replace any necessary items yourself.
