there were some threads on fluidlines in the makeup forum. here is one that i think might help you. from what i understand they are a liquid liner that you can use just like a pencil liner, but are more vibrant and have more staying power. click Here. hope this helps!!
They stay on ALL day... even on the inner rims & corners. It's a little tricky to apply.. well for me anyway - I'm better with pencils! But I use a short thin liner brush to apply it.
