I own Jerry O'Connel Small Plus wallet and I love it.
It's a palm and no palm wallet, so you get to choose which feature you'd prefer. The palm version can get the card to go into a zippered compartment, and in that compartment you pull out an I.D. case/or sealed envelope which has their signed card inside it.
The no palm feature has the card going into another zippered compartment.
No special things used there, just easier to do.
It can also be used as a peek wallet, and comes with another accessory along with the I.D. case called the wonder unit used for mind reading - excellent for table hopping.
I can't recommend this wallet enough. The wallet even comes with a dvd and a booklet that teaches you what you can do with this wallet. Once again, the best thing I've ever bought in magic.
I honestly love this wallet. It's made of genuine leather and is crazy thin for a three flap wallet. It's my favorite gimmick I've ever bought. The only downside is for the small version is that regular dollar bills don't fit in the wallet well. This doesn't make a difference to me much since showing my specs that I have money could take away from my tips. Other than that, it's all downhill.
