OPI Metallic 4 Life on wheel, Milani Gray Tux on right
I spotted this possible dupe last Monday when I stepped into Walgreens. Gray Tux immediately stood out from the other polishes in the display because it looked so much like OPI Metallic 4 Life from the Nicki Minaj collection. After comparing the two on a nail wheel, I'm pretty confident in calling them dupes. Both are black jellies with silver regular and hex glitter. Looking at them in person, I can't tell them apart. I feel pretty confident in calling them dupes!
