MAC's Style Black Collection was one of the most anticipated point makeup collections for the fall/winter season. Many Style Black products were sold out (through reservation) a week before they even appeared at MAC counters in Japan. I was lucky enough to get my hands on a few makeup items from the collection and one of those items happens to be the Penultimate Eye Liner in Rapidblack.
The Penultimate Eye Liner is a liquid, pen-type liner. When it comes to eyeliners, I find that the pen-liner is the easiest to use and the most precise out of all of the liner-types (pencil, gel, liquid liner with brush). It requires the least amount pressure and it only takes one or two strokes across the lid to achieve a bold line. When I am in need of a nice black line along my eyes, I reach for Kanebo Kate's Super Sharp Liner which is an incredibly thin and sharp pen-type liner. Penultimate in Rapidblack is slightly thicker than Kate's Super Sharp but it is also more pigmented. The Super Sharp Liner in Black is far more sheer than Penultimate and occasionally requires a few additional strokes to achieve the proper thickness and pigmentation for a natural or bold line. The Penultimate in Rapid Black comes out jet black so you only need one stroke to get a proper line. The ink also dries faster, so it is less likely to smudge or rub off, and lasts all day long. If I had to choose between the two liquid liners, I would definitely go with MAC's Penultimate though it costs almost three times as much as Kate's Super Sharp (in Japan).
It is very difficult to find many of the products from MAC's Style Black Collection but the Penultimate in Rapidblack may be one of the few Style Black items still in stock on the MAC website and at MAC counters across the world. In Japan, the liner costs 2,940 yen (including tax) but goes for almost half that price in other countries.
