I don't quite know how to explain this, but a couple of years ago I met a lady that had bright red nail polish, and every time she would move her hands, there would be a silvery "twinkling" here and there. It wasn't metallic, and it wasn't glitter. It wasn't all over the nail, either. It was just here and there. I didn't ask her what brand it was, because I thought I could find something similar, but I've tried all different polishes and none are what I'm looking for. Has anyone seen any nail polish like this?
