I stumbled upon these Maybelline 2-in-1 Impact Shadow Liner by Eyestudio at the mall, swatched them on my arms and then walked around a bit more. A few minutes later I tried to rub them of my hand and they didn't! They completely stayed put. I was so impressed. I returned to the counter and decided to pick out a few shades I would wear a lot, and I chose a shimmery white, Pearl White, and Chocolate Brown.
These pencils are so creamy and glide on your lids effortlessly. They last a long time. I put the shimmery white on my waterline in the morning, and by night it was still there. I'm very impressed, and I look forward to purchasing more of these!
Here are swatches:
