I have been on the hunt for a good liner for a few months now. I have been asking every gal I meet, what liner they use. A good friend of mine said she uses Almay, which sells for about $7.00's. So far I like (not love), this liner. The Almay website claims,
"Get beautiful definition with this easy-to-use liquid liner. Water-resistant formula lasts up to 16 hours without irritation. Unique "inkwell" design delivers fresh color every time. Flex-tip applicator provides mistake-proof control."
Well, it doesn't last 16 hours, more like 6 hours, but that is better then a lot of other products I have tried. The great thing about this liner is it's price and it is fairly water resistant. If anyone else knows of good liquid liner please let me know. The search continues, wish me luck.
