MAC Metalhead is a moderately cool-toned, dark blue with a pearl finish. It is a permanent eyeliner that retails for $17.00 and contains 0.012 oz.
MAC Metalhead Technakohl Liner ($16.00 for 0.012 oz.) is described as a "greyish metal blue." It's a muted, blackened blue with a pearly shimmer. It had very sheer pigmentation in a single pass, which I was able to build up to semi-opaque color coverage with four or five layers. It looked quite faded and softened after six hours of wear. 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.
