Mystical Realm is an icy periwinkle shimmer. That description doesn't really do any sort of justice to the polish, though! It's a very pretty pale periwinkle with a strong shimmer and a soft holo finish. While not really metallic, I did have to be a little careful while applying it to avoid a few brushstrokes, though honestly I don't think they were very visible in real life. I think I used three coats here, just to make sure I had complete coverage. I didn't have any trouble with this at all. As a side note: one of my two year old sons saw this color and immediately wanted it on his nails! Super cute!
Crystal Ball is a deep blue jelly stuffed full of tiny holographic glitter and some larger silver flakies. This is kind of blurple, though I would say it's mostly blue. This is super gorgeous. The formula was good-- I probably used three coats here again, because that's kind of my go-to number! (And also I can't remember, sorry!)
