I picked this up in Siren. Beautiful deep, teal green that wears well on any skin tone. The brush itself is probably one of the best things about this product - it's the really thin brush that can make any size line you wish - thick, thin, thin to thick, etc. NYX's liner brushes are like that and I love it. It makes application so much easier.
The product itself is beyond compare. I have very, very oily eyelids and every liner, even some liquids, tend to run and smudge after a few hourse. Pencils, gels, and creams are completely out of the question. Yes, even "waterproof" pencils smudge. Story of my life. SIGH. Anyhoo, NOT.THE.CASE with this stuff! This is the OTHER best thing about this liner. It stays put. It takes some effort to get it off - I have to use both a makeup remover cloth AND wash my eyes after to remove all of it. Sounds like a pain, but it's worth it if your lids are like mine.
