I have been using the Kat Von D Tattoo Eyeliner in Trooper. I love it, so easy to control, stays on all day and water resistant. Its $18.00 at Sephora, but it's worth it. I have had mine for months. They also have other colors available. If you’re not looking to spend that much on eyeliner another brand I like is the L.A Girl Fine Line. I got this for $5.00 at Hot Topic. I like this one as well. The brush tip is so thin and easy to apply.
