I was using BLUE HEAVEN EYELINER some months before. This is an average eyeliner.
I should say it is for beginners who are starting to learn how to apply eyeliner without having the feeling that you are wasting something.
This is not so costly and neither hard to use. It comes in a some bottle like nail polish but with a different kind of brush attached to it. The strokes by this are good though.
I must tell you that it Don't stays too long.it is good for only three to four hours maximum. Average Black in color.
In cheap prices a nice product to use.
I personally didn't notice any sensitivity problem. My skin type is normal.no irritation n all.
