Best glitter eyeliner I've ever used. Looking at some of the negative reviews here, it's hard to believe that they are talking about the same product. I find the application to be *really* easy, I've never had any flaking, no irritation whatsoever. You do need a heavy duty make-up remover to remove this gently, but that's only to be expected because of the large chunks of glitter. I have several Urban Decay and Too Faced glitter eyeliners, and these are *so* much better. They're also much much better than other cheap/teen companies.
One of the things I like the most about them compared to other brands is that the brush picks up a LOT of product. People generally want to wear a glitter eyeliner when they are going out and want to get noticed, so what's the point of having a glitter eyeliner with a thin brush that only picks up like three pieces of glitter with each dip? (This is one of the things I don't like about Too Faced liners.) You can still draw a thin line with these if you're careful. And you can draw a thick line or use them all over the eye as an eyeshadow *really* quickly. The glitter is often of a more complex shade than those of other brands, the colours are very intense, and the staying power is insane.
My favourite shade has got to be Shake It Up!, it's a bright purple/blue that looks great with my brown eyes. I love wearing this when I'm going out, I just put on some primer, bright purple eyeshadow, black eyeliner, and then this all over on top of the eyeshadow and eyeliner. It stays on FOREVER, like, literally, all night and all of next day, even though I have very oily eyelids, and looks absolutely gorgeous. I also love Rock Chick, a black with silver glitter. I use it with the purple as an eyeliner, or on its own, on top of another black eyeliner, with no shadow. Worn alone it does indeed look casually rock chick-like. Dig It! is great too, it's a black with gold glitter. And then there's always Dancing Queen, which is a bright fuschia pink with complex coloured glitter. All in all, these are glitter perfection.
