MAC Coin Operated is a moderately warm-toned, dark gray with a pearl finish. It is a limited edition eyeliner that retails for $17.00 and contains 0.012 oz.
MAC Coin Operated Technakohl Liner ($17.50 for 0.012 oz.) is described as a "metal grey with silver pearl." It's a warm, gray-taupe with a pearly sheen. It had semi-sheer pigmentation in one pass, which was only buildable to semi-opaque coverage. It did have more creaminess to it than other Technakohls, though the texture was more wax-like than truly creamy. It lasted for seven and a half hours on me.

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.
