MAC Superfly is a neutral-toned, very dark black with a satin finish. It is a permanent eyeliner that retails for $17.00 and contains 0.012 oz.
MAC Superfly Technakohl Liner ($16.00 for 0.012 oz.) is described as a "soft black." It's a rich black (not a soft black at all, actually) with a satin finish. It had a waxy feel to it, but it was buildable to opaque color after two layers. The eyeliner looked softened and smudged after six hours, though. See comparison swatches / view dupes.
The liner’s enduring formula features a unique combination of plant-derived waxes, providing a soft, comfortable feel, while staying smudge-resistant for up to eight hours. Whatever your style, get ready to line it up.
