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).

Swamped ($17.00 for 0.01 oz.) is described as a “deep khaki green.” It’s a muted, medium-dark forest green with subtle, warm undertones and a sparkling, pearly sheen. It had semi-opaque coverage in one stroke, which built-up to opaque coverage in two layers. The consistency has noticeable sparkle, so I’m not sure if it’s truly recommended/safe for the waterline (the formula is supposed to work for the waterline). When I tested it, the color lasted for four hours on the waterline and about eight hours on the lower lash line, but there were some flakes of eyeliner at the six-hour mark.

Polar Ice ($17.00 for 0.01 oz.) is described as a “pearly white.” It’s a medium white with cooler undertones and a mostly matte finish.
