Ohhhh, myyyy. A gorgeous, burnt red-orange, shimmery foil with a kind of blackened undertone that shows up in some kinds of lighting, though not really strongly enough to call this a duotone.
Application is straightforward, nice formula, neither too runny nor too thick. One coat might be sufficient if you're good with a brush, but two coats will definitely give absolute opacity. Removal is pretty typical for a shimmer-foil (lots of tiny glittery bits everywhere, but otherwise fine).
I've heard a few reports that this can stain, and while I haven't experienced that, myself, I recommend making sure you use a good base coat that you know will protect your nails, as this really is a highly pigmented polish with a lot of rich colour.
