This is my go-to eyeliner!It's cruelty-free (a requirement for me) reasonably priced well-pigmented easy to apply (I have impaired vision and the use of only one hand) and it wears tenaciously on my insanely oily skin.The tip is super-fine which lends itself to creating a subtle tightlined effect.I'...

This is one of the best eyeliners I've ever used. I have hooded eyelids and always had a problem with my eyeliner smudging when I closed/opened my eyes. This dries so quickly and doesn't disappear. This one is not the waterproof version but it stays put and holds up against tears smudging etc.

Barely makes any line. Product does not come out at all.

I was looking for a dark brown liquid eyeliner and saw that this was on sale last week and I remember an influencer mentioning that this is one of her favorite drug store eyeliners so I decided to grab it. I LOVE it. This doesn't skid due to the brush tip. Very easy to apply a liner even with my shaky hands. The color also doesn't fade over time. Would definitely purchase this over and over again.

The pen writes nicely and it is easy to be precise
Fun to use, wish it had better staying power
I can easily do any variety of styles with this eyeliner, it glides so smoothly and gives a nice defined line that doesnt need much filling in/touching up - I am a perfectionist with my eyeliner and found that this lasts throughout the day when used with a primer but only above the lids. It's hard to find something so permanent that the wings at the ends of your eyes stay all day. It is so close to being the perfect eyeliner and for a daily minimal look it would be perfect!
