I think its a brilliant principle but is some what limited to what surfaces you can do it on. My
biggest complaint is about the materials needed to make the gimmick. They list only one supplier in
the US (another in Spain)and the shipping costs are more than the material is worth. Very high
16-25 dollars JUST to ship plus cost of material. When I do the math it increases the price of this
effect to 3 times what I paid for it. Its not something you go to your local office store and buy.
Also there are a lot of other materials on the market that appear to be the same but do not work
.Its a very specific material so be cautious. Its do bad Penguin does not order this in and bulk and
offer it.
