It's more turquoise than the others (yes, yes there is a difference) and it way more opaque. It reminds me of an interior of a diner or an old-timer car of the sixties.
The brush is a new one - it's way more wider and the lacquer needs only two time applying.
Cause my nails constantly brake since a few weeks, I got a new base lacquer: Essie Nourish Me, which is an intense hydration base coat that should prevent splitting. I'll let you know in a few weeks if it works. Unfortunately the brush is not a wide one, just an ordinary small one.
