I've been consistently using Merzy brush pen eyeliners for several years now. I like that the thickness of the pen is just right—not too thin, not too thick. The staying power is also longer compared to other brands, which I think is because it is resistant to moisture and oil. Of course, it comes off easily with oil-based cleansing products. There is a wide variety of colors, but I really want to recommend No. 2 Brownie because it looks so natural!!
