I've definitely swatched this before, but layered. Here it is almost on it's own. I used the Ozotic to hide a little bit of the VNL, because sand-erella is gorgeous but really sheer, and gets a little bit expensive at 4 coats. This one smells funky >.< and by funky, I mean toxic; it's one of the oldest OPIs I own. Must swatch in highly ventilated area for sure. Lately I've been obsessing over holographics. I hadn't revisited this obsession for a while now. I'm not sure how long it will last, but for now let's enjoy the rainbows!
