From the Essence website: "The new glam liner ensures a glamorous appearance wherever you go! it contains shimmering pigments to reflect the light for a unique interplay of colors with ingenious effects! liquid but quick to dry, you're sure to achieve the popular glam style in a flash thanks to the ultra-accurate applicator."
These really do sparkle, I took two pictures - one normal and one blurred to show the sparkle. I really love the applicator, it's very thin but flexible to ensure you have a precise, fine line. I borrowed the last image on the bottom to show you just how ultra-accurate that applicator is! For those of you who have access to these, grab them! Dee picked these up for me in Germany, but I know they are sold throughout Europe, and Erika just told me they started selling Essence in Ulta, so be on the hunt!
