An often-used phrase I see with some effects is that you are "only limited by your imagination". That certainly applies here, because you really do get to accurately read someone's mind; they can choose a card, they can simply think of a card, they can think of their favourite colour, the name of their first pet - literally ANYTHING you can think of to ask them, and you'll get it right. The wallet provided is excellent quality. The only remotely negative thing about it as that I would have liked it to come with one or two spare 'target' stickers, as I accidentally made a bit of a mess of mine while practising, so it would have been good to be able to replace it. But that is a real nit-picky point, and certainly not enough to make me not give this five stars. I performed this within a short time of opening the package. Being a 'Doctor Who' fan, I told someone I had some Psychic paper in my wallet, and that I'll be able to show them what they are thinking of. I was about to ask the person to choose a number, but she jumped the gun and threw a random word at me (trying to be clever - she thought!) I said "OK, that isn't what I was going to ask you to think about, but that' s Ok. Focus on the word....." and I ended up handing her a business card with that word on. To say that the reaction was jaw-dropping is a massive understatement. Really recommend this. It really is a superb effect. Tutorial is clear, with some ideas on several different presentations, but in terms of what you 'predict', it really is right up to you.
