I use this every day, and can't believe I am the first to review it.
It is so creamy. I use an angled eyeliner brush to apply it, just like a fluidliner. It is also great if you want to smudge it.
This liner is amazing on the water line, but the only thing I would not recommend it for is hooded eyelids.
I have Onyx black, and I love love love it.
