Nfu Oh 61. Silver holographic. This is the "dud" foil version but I rather like it. I am a huge fan of foils, so what more could I want with a foil that is holographic?! This is two coats over Nfu Oh Aqua Base and without topcoat. This is my first Nfu Oh holographic if you can believe it. I have a lot of their foils and a bunch of cremes.
