MAC Modern Twist Kajal Liner ($17.00 for 0.01 oz.) is supposed to be an “easy-glide formula” with a “soft texture that’s perfect for rimming the sensitive waterline” that has “colour intensity and extreme depth” in a “long-wearing waterproof formula.” It’s a slim, twist-up eyeliner thas has light slip–not enough to slide around too easily but enough not to tug–with semi-opaque to mostly opaque coverage in one stroke. They felt creamier rather than waxy to me. On me, the formula wore between six and nine hours on me before noticeably thinning. None of them lasted for more than a few hours on the waterline, and some shades applied better/worse on the waterline. Some shades flaked while they wore, between four and six hours in (noted by the shade).

New Marine ($17.00 for 0.01 oz.) is described as an “emerald green.” It’s a medium-dark, bluish-teal with cool undertones and a pearly sheen. It had semi-sheer coverage that was buildable to mostly opaque coverage after two to three layers. The consistency glided on easily without tugging on the lash line and deposited color fairly evenly. This shade flaked away as it wore down, rather than just fading away, with noticeable flakes after seven hours of wear on the lower lash line. It lasted for four and a half hours on the waterline.

Nightcast ($17.00 for 0.01 oz.) is described as a “grey muted plum.” It’s a muted, medium-dark purple with neutral-to-cool undertones and a matte finish. It had semi-opaque pigmentation in one pass, which didn’t built up much beyond that but seemed to darken and intensify slightly by layering. The color lasted for eight and a half hours on the lower lash line, five hours on the waterline. ColourPop No Shame (P, $7.00) is darker (85% similar).

Ocean Liner ($17.00 for 0.01 oz.) is described as a “deep blue.” It’s a dark, navy blue with cool undertones and a subtle, pearl sheen. The consistency wasn’t too waxy or too creamy, and the eyeliner glided on without tugging on the skin, even though it didn’t have great color payoff in one stroke. It was buildable to fuller coverage, but it was hard to get fully opaque coverage. It lasted for five hours on the waterline and eight hours on the lower lash line, but it started to flake after six hours of wear. Buxom Pick Me Up (P, $17.00) is more shimmery (95% similar).
