I like this eyeliner. goes on very easily, smooth. i gave it 4 stars only because have to be careful taking brush out of the (flat/sort of odd) bottle, or too much product on the brush and it can "glob". Seems to stay on all day too. Otherwise, nice. I have been using Lancôme "artliner" liquid eyeliner for the past few years, but trying this now; on my 2nd week.
I have used the Guerlain Liquid eyeliner for years now & it continues to be my favorite! The long handle allows easy application and the color is true to what is show. My preference on this liquid liner allows me to have perfectly lined eyes, without having to pull on my eye lids.
The calligraphy-style pin took a little getting used to, a few days of practice and I was ready to go. I can easily create a thin line or defined cat eye with a single tool.
This eye liner last all day and stays in place. It also easily washes off at night. Rarely do I have to touch it up, even after long days at work and going out at night.
