Urban Decay Studio is a slightly warm-toned, light-medium lavender with a glitter finish. It is a permanent eyeliner that retails for $21.00 and contains 0.25 oz.
Urban Decay Studio Heavy Metal Glitter Eyeliner ($21.00 for 0.25 oz.) has a clear base with lavender sparkle and holographic glitter. It had semi-sheer coverage in a single stroke of the included applicator. The texture was watery, lightweight, and thin with a fairly quick dry down (didn't feel too fast nor too slow). The glitter moved evenly across the area I applied it to, so it had a good effect all over. It lasted nicely for eight hours with very minimal movement over time.
