Over my several month purge effort, I've gotten rid of well over half of my Nfu Ohs. I either had dupes, the formula was deplorable, or I wasn't feeling the color enough to see myself ever wearing it again.
This one was the first in the keep pile. I love an almost black. This is a particularly good one because the base color (which you see in the first coat) is a vibrant cobalt blue. It gives the mani a glow even though the ultimate color is very dark.
(3 coats)
This is three coats but I actually wore it as just two (I sloppily applied a third coat because there was two days wear and I didn't feel like showing off my tip wear). It dried very well (unlike the majority of my Nfu Ohs).
