I can't seem to find a post on this. I've been wondering where I can get information on the rose through the palm of the hand trick. Any info would be greatly appreciated.

To tell you the truth, I don't think there is such an effect on the market available to purchase. I have seen the trick performed online in a demo video by a magician
(pm me for the link and his name) But I have never heard of that trick being available through dealers. Where did you see it?
