You only get ten ESP cards and a few extra ‘specialty’ cards in this “deck”, (such as a double
backer, (which is clearly not marked, and can come in handy); a couple of double facers; a card with
what looks to be a giant “D” on it; and a card with all the symbols shown in order, in a single line
on the front of it). The cards are white plastic and will last a lifetime. No uneven wear, no water
damage worries, easily washable. The markings are simple and easy to read, while still being
deceptive enough to go unnoticed by spectators handling them during your performance. If you have a
routine that uses 5 or 10 marked ESP cards, you can replace those cards with these, (as I have
done). One more positive feature: The packaging does not give away any relation to magic or
markings. It’s a single piece of card stock that folds into a box with a tab/tuck closure. It
indicates that they are Zener ESP testing cards and that they are Rhine Research Center Approved. It
looks official and legit. …If only the ‘box’ were also made of plastic, (this card stock will wear
out fast). If this box maintained the graphics on it and was instead made of plastic, these would
be the perfect set of ESP cards. Couldn’t be happier with this purchase.
