Ok. I was just flipping through the pages when my i cought the effect called "Great Minds Think Alike" By Punx. I dont want to expose too much but in the effect you need a special paper which leaves a shiny line when you drag your nail on the surface. So i just ran my nail on the corner of the page paper. And what do you think? It shines! I will have to find exactly the same paper to perform the effect. Its funny that the answer that i have been looking for is the book itself.
