Urban Decay's standard pencil eyeliner is their 24/7 Glide on Eye Pencil. Currently, they offer 23 shades as part of their core collection, with limited edition or exclusive shades for certain retailers. They introduced 3 shades this spring, however, they've skipped over Whiskey (again), offering a shade that looks similar - Demolition. I may pick it up at some point, but not today.
Sephora's website says:
Glide on color that stays put for the duration of your non-stop, on-the-go day! These cushiony, creamy eye pencils deliver powerful, vibrant color that slides on smooth and stays soft and creamy for blending (about 30 seconds), then dries to a long-lasting finish that won't budge. Line eyes with a hint of color or go for the full artistic, multi-hued effect. Truly inspired, these pencils go all day and all night.
I'm hoping UD will come to their senses and release it as a standard color, because it's perfect. It accentuates the green in my eyes, and is easy to wear. 24/7 liners are worth the price, however, I would swatch before buying, as some colors are less pigmented than others. Underground, for example, isn't terribly pigmented on me.
