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).

Black Walnut ($17.00 for 0.01 oz.) is described as a “brown-black.” It’s a medium-dark black with warm, brown undertones and a semi-matte finish. It had semi-opaque coverage in one stroke, which was buildable to opaque coverage with two passes. The consistency didn’t drag on the lash line, but it wasn’t really wet or emollient (usually a good thing!). It lasted for eight hours on the lower lash line, four hours on the waterline.
