Parlour cards are designed for stage work. They're highly visible at long distances; and they do this by being 1/2 inch wider and 1/2 inch longer than standard poker size cards. These have "Phoenix" backs, in red or blue.
Anyway, allegedly you can do all your standard sleights with these cards (just try that with Jumbo cards!). So, first impressions:
Very nice, high-quality cards. They faro like a dream. Each pack has two jokers, plus two cards useful for Skinner's Ultimate Monte. The backs are marked; the backs and faces both have one-way designs. (These are, in fact, designed for magicians.)
As to what sleights I can and can't do with them: first, most importantly to me, no problem with the sleights required for Victor Farelli's "Thanks To Leipzig," that trick is the reason I bought these cards in the first place.
Of the other sleights I've tried (assorted passes, top change, glide, side steal, etc._, the only ones I don't have working yet are the Ultra Move (doubt I'll ever get it with these cards), and, surprisingly, the Charlier Cut. If I play with it enough, with finger position and such, maybe someday, but not yet. I can, in fact, do a front flat palm, but I also have very large hands.
So, I'm glad I have these, and will be using them whenever I'm in a stage situation.
