‘Fly’ is PERFECTION!! An electric azure shade of blue, it bears an incredibly smooth formula of medium opacity, that not only levels itself, but leaves behind an ultra glassy finish. An interesting paradox is that while at first glance this colour may appear as too bright, once applied, you realize that there seems to be a slightly muted cast to it, making it so appealing. With two coats, complete opacity is reached, giving excellent coverage and I found that the dry time was definitely on the quick side. Bonus: no staining left behind at all.
