The best liquid eyeliner. Goes on smooth. Can make the line as thin or as thick as you like. Stays on all day, never smudges or runs. Removes easily with gentle makeup remover. Last a long time!

The bristle of the eyeliner is flexible and allows smooth lines without them being jagged. Stays on all day.. having been using for years and have tried other options but this is is best

Lasys for more than 24 hours

I hesitate to review before using this for a while. I hope it lasts as long as my first purchase at Ulta. Time will tell. I love this brand as the liner goes on so smoothly, doesn't drag on the lid.

I love the product itself and have been using it for years. You get crisp lines and it's a long lasting eyeliner. However, when I.T. changed the packaging to a slim version (previous version the top and bottom was more flared out), I noticed the pen runs out of liquid far quicker than the previous version and is also prone to leaks. I had to return 1 out of the 3 pens I bought due to a leaking issue. I find myself purchasing the product more frequently which I don't appreciate (likely the cartridge capacity shrank). If they can address the leaking issue that would be ideal. I recommend the pen itself but sometimes you may get a defective product.

Excellent. Stays on well and easy to apply.
