MAC Royal Wink is a very cool-toned, medium-dark blue with a matte finish. It is a limited edition eyeliner that retails for $16.00 and contains 0.1 oz.
Royal Wink is described as a "bright ink blue." It's a bold, brightened cobalt blue with a satin finish. It had rich color payoff but had a slightly more emollient consistency so you have to be careful not to go back and forth, as it will sheer out if you do so--it goes on fairly evenly with more opaque coverage in one stroke. It wore well for ten hours on me. Get comparison swatches / compare dupes side-by-side.
