I buy tons of magic and rarely write reviews but I think I'm going to start now.
I am
extremely impressed with the quality of the gimmick. The reactions have been absolutely stellar.
You can get fancy with your moves by snapping the card, flicking the dots, shaking the card Etc.
Sometimes I simply blow the ink to the other side of the card. Watch the lighting but it shouldn't
be an issue if you are constantly moving your hands around.
Highest recommendation.
