The best matte black base I have ever used!
I have tried other matte black gel liners as a base and they always end up creasing or blending away in chunks, and my lids aren't too oily either. The Tar Smudgepaint doesn't flake while blending and lasts all day without creasing.. I usually apply with with a fluffy synthetic brush and apply it semi-sheerly on top of an eye primer. It can also be applied opaquely as a liner. My only complaint is that I wish there was more product for the price.
