Mac eyeliners are the only eyeliners I own, so I certainly love them. They all go on smoothly and can be blended out or left alone and will stay put for hours. This particular color, Petrol Blue, was given to me from my sister (never share eye products).
Little did I know, that this color had dried out. How that happened is beyond me, but I had a very hard time getting the color to show up. When I could, it was a very dark navy, nearly black. The name is very fitting. It would have been the perfect color to line your lashes with and it's a subtle change from the standard black or brown.
What are your thoughts on MAC liners?
