Purple Potion is a purple glitter suspended in a black jelly base. It looks very similar to another Wet' n Wild polish that they have out, but I can't remember the name at the moment. Hmm.. anywho it is a beautiful polish. In regular lighting it can look pretty much just like a black polish, but in brighter lighting and in the sun? Well, its super sparkly. It did dry to a matte and gritty finish and could have used two coats of top coat, but I only used one of Seche Vite. I did three coats because at two it did leave a few bald spots since I had a bit of trouble applying this polish. I had to put at least eight drops of thinner, if not more, and it was still a gloopy consistency. Also, the brush didn't help, it had several stray bristles that I had to cut to make the brush a bit less crappy.
Being that this polish was only 1.99, I'm not complaining. It was a really nice polish and according to my husband, it was a badass color. He doesn't say this about many of my polishes, so this is a keeper for sure.
