This is the clear version of the flakies from the Opal Collection. I had posted a review of the green one earlier here. This one was similar in formula and the finish varies depending on what you use as a base color. I find it that it glows more bluish tones when layered over dark colors. For the Winter, I think I prefer it over pastels and muted purples as shown here.
