This is a gel eyeliner from UOUO. It comes in a box with a little brush.
I absolutely love this eyeliner. It's a smooth, almost creamy gel texture, pretty identical to Maybelline's gel liner. It is really easy to apply, and doesn't take very long to dry down at all. It sets really well, actually, and it's very black. I did get 10+ hours out of it, and even then I had to work a bit to remove it. Another nice product from them.
