It's an authentic product. I like the colour, I put it after my Urban Decay Mildew (sorry!) eye-liner, which I smudge a bit like a shadow, This then goes on my waterlines, which highlights my steel blue eyes beautifully. I like that I don't need to sharpen it. This doesn't smudge unattractively under my eyes, keeps the whole day, even if I cry outdoors. It was an outstanding value as well from this vendor.
