ColourPop Polar is a cool-toned, black with a sparkle finish. It is a limited edition eyeliner that retails for $6.00 and contains 0.11 oz.
Polar (Creme Gel Colour) is described as a "true black with multi-coloured glitter." It's a plum-tinged black with large silver, green, and violet glitter. The texture of this seemed dry to me; it was noticeably less creamy compared to the majority of the shades I've tried in the formula. I felt like this made for eyeliner that applied in dragged lines, where the edges were splayed and the color was uneven. The underlying black base lasted for nine hours, but there was fall out and migration from the some of the sparkle. With some sort of mixing medium, this might be workable, but just as-is, the dryness made it problematic. Bobbi Brown Twilight Night (P, $23.00) is lighter (90% similar). MAC Black Swan (P, $15.00) is less shimmery (90% similar). NARS 47th Street (LE, $24.00) is cooler (90% similar). Urban Decay Ether (DC, $22.00) is lighter (80% similar).

Precision of a liquid with the ease of a gel based formula. Apply with a brush, we like a super fine, firm and synthetic angled brush. Dip tip of the brush, coat both sides – be careful not to pick up too much product! Work quickly, as the formula becomes transfer resistant once it dries. Do NOT leave opened for long periods of time or it will dry out and you will be sad. Be sure to close the lid tightly after each use.
