Formula on this was good. It is nicely pigmented, though had a little bit of a jellyish feel to it compared to some of her other holos. It was still easy to apply, the first coat did want to streak a little if you applied too much pressure. Two coats gave good coverage but I ended up with three because of my large nail beds. It dried down quickly which I always appreciate.
I really like Summer Skies (both in reality and on my nails). It's a beautiful blue, and although the pink shimmer isn't really visible in my photos here, it's a really nice addition and gives the polish more depth. All in all, another nice addition of the CbL POTM line-up!
