Magic Tricks

Exactly what I wanted -- standard ESP cards with a nice, hidden marking system (I find some markings on other decks to be way TOO obvious). These markings shouldn't be noticed by anyone, despite being in four places. The markings are similar to a clock, so they're easy to read, although they might be too small for some people. (If you need to read them from across a room, maybe look at Eclipse.)

As mentioned, this is a set of FIVE cards, but with penny arcade I was able to get two sets for $1, which is what I needed for a routine.
