A soft medium grey holo wrapping multiple reflections.
The novel itself! This for me is the standout polish of the collection, I love greys anyway and this is just perfect. A warm grey leaning towards a purple undertone with hints of silver and occasionally other colours when caught in the right light. Easily one coat and you're done.
Available as a full bottle if you've fallen in love already or as a sample strip if you're not sure. Remember all sample strips have free shipping.
