This microliner is the only eyeliner I have found that glides on easily and stays on all day without smudging or flaking. It also comes in gray, which is a rarity in eyeliners but a great color for fair skinned people with light colored eyes. Black can be too harsh. Sadly, it has been discontinued, but I was able to buy a couple on eBay to keep me happy until I can find a replacement. I still can't figure out why it was discontinued.
