Zoya Armor Top Coat 0.5ozArmor indeed!
Zoya`s polishes last longer than most without the top coat, but with it - oh my, the polish lasts much longer. I spend 3 days a week in pool classes and the chlorine has no effect, my nails stay shiny with no fading, or discoloration. Actually, most of the matte finishes can resist chlorine anyway, but this top coat makes my nails like armor. no, really! Easily 2 weeks before I take it off.
