I love this eyeliner the most out of all my eyeliners.
Its generally long lasting and easy on the eyes. Does not smudge that easily but if you draw out of the line its very easy to just dip a q-tip/cottonbud in water and dab it away.
It has a felt-tip application - smooth. precise. (hard as first but will soften with time)
When it gets too thick its probably time to get a new eyeliner =X !
Also, it doesn't hurt my eyes when I waterline which is a big plus for me ..cause then the rest of my make up runs T_T
Practice with it and you can get very used to drawing lines in seconds..
It comes in Black or Brown~
I know the review sounds abit like an ad...but I love this eyeliner
Been using it for 3+ years without problems
Also its suppose to be one of their popular items ^_^
