honestly, i hate to say anything negative about my penguin magic purchases because they stand behind their products & only sell the best. however, i'm disappointed with this particular product. there are no real instructions on how to actually implement the effect. just suggestions for presentation.
this one should come w/ video instruction.
worst of all, the material (laminated plastic) can give a nasty paper cut. i sliced my finger pretty bad trying to figure out how the gimmick works.
unless you're already familiar with this effect then i wouldn't recommend it.
