You can have the spectator select a card with the help of this pen, which you have of course predicted and will show at the end of the trick.

The spectator can arrange the order of the ESP cards by chance, which matches the order engraved on the pen!

A prediction can seem false at first sight... But the ink vasnishes when it's in contact with heat, which makes the prediction right!

A great little gimmick by itself, but you can combine the E-S-PEN with other mental tricks, like ESP cards, enchancing the effect!

Without instructions.
