This is Megalast On A Trip and Sephora by OPI I Don't Bite:
This is two very different takes on blue-violet. On A Trip is a creme in a lovely blue-leaning violet, while I Don't Bite is a grayed-out near-metallic - you might even call it a glass fleck. I've seen swatches where it even looks like a frost, but it didn't come out that way in my swatches. Neither one of these polishes is available, I'm fairly certain: SOPI is out of business unless you can find a stray bottle still hanging around in a Big Lots bin. And On A Trip was one of those seasonal limited editions that they love to do with Megalast.
