Glides on and has dark formula
"I am really picky when it comes to liquid eyeliner. I prefer a brush tip in a bottle I can dip into, so I had hesitations when seeing this product in a brush pen. The ones I have used in the past have usually dried out after 3-5 uses and tend to bleed because of the thin formula. This Revlon eyeliner was not like those other ones - the formula was dark and rich, and glided without settling into the fine lines on my eyelid. If I made a mistake and needed to wipe a small amount off, it didn’t smudge the rest of the line I had just drew (the formula dries fast!). I didn’t have to store it any particular way (standing up, tip down, etc) and it was a nice surprise to have it last so long."
