I actually purchased this just to get the brush! I was surprised how much I ended up loving not only the brush but the gel liner, as well! I own several of BB's gel liner & 2 of her eye-liner brushes & am never thrilled with the look I get using BB's gel liners. L'Oreal Infallible Gel Laquer Liner in Dark Slate took me by surprise because after plunking down lots of cash on BB's gel liners & not really liking them, I was done w/ gel liners. I really like this gel liner. It's a unique "slate" color-not silvery, no obvious blue, more of a warm, deep grey close to a greyish taupe. \I have green-blue eyes, fair-light NC20-25 skin & this color looks just right on me-not too harsh & not too light. The liner itself is creamier than BB's which allows for more control in application (I like to smudge a bit-HATE a solid line on my eyes). I have dryish skin so staying-power is not that big of an issue for me but so far this seems to have great staying-power & has not faded a bit in 8 hours. Oh & that brush that brought me to this eyeliner in the 1st place, is great. It's exactly what I wanted. Very good product, Dark Slate is a great color and the packaging is high-endish (reminds me of BB's but L'Oreals IGLL's pot is lighter & seems less bulky). All this & the price is less than 1/2 of BB's (plus w/ L'Oreal IGLL's you get a great brush).
