I've used Sayuri Fro Cone polish as an accent nail in a previous mani, but this time I made it a star. It takes quite a bit of building up to opacity. I didn't have much time for this, as I was doing it right before bedtime. So I thought I'd use it as more of a glitter topper. The base was one of those random Five Star polishes my Mum picked up from Aldi's (haven't seen them recently, don't know if they'll restock them).
It worked pretty well and the the pick really popped.
