Inside this collection are ten sets of special cards, with just a few cards in each, which are used for performing specific tricks, although with some of them the cards can be used for many more of your own invention. Most of these sets produce fairly good effects, and the tricks for a couple of them, namely "Colour Changing Kings to Aces" and "The Incredible Jumping Jack", are easy to perform and very impressive. Some of the others require a bit more practice, but it is worth it for the results.
Also included are two decks of cards, a Svengali one and a regular one, and handily enough the design on the back is the same for each (and it actually looks like the back of a real pack of cards). This is also the case for the special cards mentioned previously, which is useful if you are performing a mixture of tricks. A special box is included which (among other things) is used to switch the gimmicked cards for regular ones, although it is a bit too small to easily get the cards out afterwards, and is also unnecessarily deep when it is being used to switch cards.
Full instructions are given for all the special card sets, along with a guide to many more tricks and information on card handling techniques. All in all this is well worth the money and provides plenty of fun.
