For the price you can't really go wrong if you're looking for marked ESP cards. The four included
gaff cards come with an example routine, on top of five full sets of both marked and unmarked cards.
You will need to know an ESP routine of your own to get the most of this pack. They're not Bicycle
quality, but they don't need to be for my purposes. This pack will likely last me a good five to ten
years of use before I wear them all out. That'll be dozens if not hundreds of performances...for $10
worth of props.
