Wow! If you want glitter liner, this is the real deal!
"Glam Rock" is one of the newer shades, and it is PACKED with very fine, BRRIGHT silver glitter. The glitter is suspended in a clear gel-like base, so you don't get a solid line of glitter with the first swipe.
Just one more layer, however, gave me a nice thin line of twinkly silver glitter, just under my lower lashes. I'm still trying to decide if I can pull this off for dressier daytime occasions. It feels fairly wet on application, but once dry, it mostly stays put. I *do* notice some minor fallout, but much, much less than is typical of loose glitter. I didn't put on any primer, either.
I gave this a 4 because it's pretty enough to deserve a high score, but is almost surely not for everyone, any time of day. I'd buy this again if I ever run out, since I adore silver.
UPDATE: I'm raising the score of "Glam Rock," because it's the best silver eyeliner I've found, and I've tried plenty. A thin line under lower lashes only gives my eyes a subtle sparkle that's low key enough for day.
That said, I should add that this does not hold up well during a hormone-induced crying jag, so it's best not to wear this unless you're feeling very stable. Under normal wear, it's a lovely and very fun product.
