This was a big surprise when I got it, the quality of the wallets is good so much so I now use this as my everyday wallet.
You can do a number of effects with it none of which are that difficult.
It does require a little bit of practice to get used to the handling but you will soon have it working for you.
The thing I love about this is that it is now my normal wallet, so if someone says show me a trick or hands me a deck of cards I can perform a number of very strong routines all using the wallet.
Just imagine you are out someone gives you a pack of cards and a chosen card ends up unside the smaller wallet in your wallet.
Then you borrow a credit card or ID and go about a routine telling them facts about themselves, the facts are wrong and you notice it's your card in your hand, their card is now inside the smaller wallet!
You can then do a gambling routine Wack Your Pack which does require you to be able to do a DL, but again a really strong effect, where they grab for a card they saw on the table but it's the wrong one, the one they saw is now in the wallet.
You can also produce things from the wallet, but for me the above three routines work well and I could go around tables all night just with my wallet and a deck of cards performing some very impressive magic not just card tricks!
Overall this is very good and not hard to do.
