Today we have Ozotic 534. Yes, I'm a jerk for posting this after they've been discontinued, and probably aren't for sale anymore.
This one is from the Mish Mash collection, which are duochrome and holographic. This photo doesn't even do it justice.. it's so hard to capture the duochrome in it. If you can believe it, it flashes to a burgundy, blue, and purple (as you see in this pic). Mostly the color flashes are in low light, when the holo is not as noticeable. But it gives the holo particles such a great depth, the way the polish seems darker around the edges. Seriously, this is beautiful!
