The application is amazingly smooth, and the product is very pigmented. This claims to be long-lasting, and I must say when I wear this on my upper lash line, it does last all day. It may be smudged a little at the end of a long day, but the color is still vibrant and it holds up well on my oily lids. On my lower lashline however, it smudged really badly even with a primer. I only wore it that way once, and while it looked good at first, within a few hours it had smudged and looked like a mess.
Overall I really do like this eyeliner and I'm glad I got to try a sample of it. I'm definitely thinking about getting a full sized one in black too. Anyone else a fan of these?
