I recall mentioning (here) that I have come to a point where I don't think I need 20 silver holographics, because at some point they all seem the same. However, this is the exception, this is very different from any other silver holo I've seen. I love it that it's not gritty, even though it has lots of glitter in it. The holographic effect is very strong and the rainbow is somehow undisturbed by the glitter as well.
