I wanted to find a eyeliner that is a rich black color and stays on all day long. Surprisingly while at CVS I found and bought L'oreal HIP cream eyeliner. It's a great true black that goes on creamy and lasts a long day (until you remove it) it's great for a day look and to accentuate a smokey eye for a night look. They come in other great colors too that I have to try because I love the black!
It comes with a little brush that is a bit hard but workable. It's angled perfectly to apply the liner and small enough so it's not clumsy. You can always use any other eyeliner brush because the product is really richly pigmented and great! Lets not forget pretty cheap (around $12).
UPDATE: This product dried out after a few weeks :( making it totally unusable.
