Save Any Nail Polish That Has Gotten Too Thick With Fluid-E From Essie by Chelsea West Save Any Nail Polish That Has Gotten Too Thick With Fluid-E From EssieThis stuff is a life saver, Essie brand is amazing and this just makes me love the brand even more! I use mine on my other brands too and it works better than nail polish remover or acetone the original solvent in the nail polish evaporates over time, which is what makes it thick, this adds it back!
