@santorini YES ... it lasts FOREVER. The flow is constant which makes it so easy to draw your line ... as thin or thick as you like. I line the top and bottom.
Have been searching for a liner like this for years and FINALLY found this. Was using a liquid decades ago, and then when it was discontinued I switched to BB gel eyeliner. I had to find the right brush for that and then it would dry out way too soon. Then I went to the Clinique cream liner in a pot ... another excellent liner, which lasts a long time (but I think has been discontinued).
Then about 2 years ago, a friend of mine who doesn't wear make up, was given this (Pretty Easy liner) at a dept store and she gave it to me. SOLD! There was no turning back. THE BEST BEST BEST! Wish it came in a deep brown, but it doesn't. The regular brown, when you can find it, is not as great as the black.
I LOVE THIS LINER! I have a few stashed away ... just in case!
