This is probably the nicest blue nail polish I've tried. Granted, I'm not really into blue polish in general, so haven't tried a whole lot of them, but this one is a true beauty!
With 2 coats it gives a really nice deep matte look. It goes on a little bit thick, so I can see where I painted my nail unevenly. I managed to wear the polish for four days without tip wear or chipping, which really surprised me.
Overall this polish is really beautiful, makes me really excited about other blue polishes out there, I love it!
