I ended up going to the opthamologist after using this product for a while because my eyes were SO red and I could not stop itching!!
Dr. told me I had an eye infection in both eyes and a rash on both of my eyelids! 2 weeks of steroid drops and creams (and of course, no eye makeup)....
Will not EVER use this eyeliner again!

Classic, reliable, everyday liner. Nothing too dramatic. Goes on smoothly.

Love it because it stays on my waterline! Definitely my holy grail waterline eyeliner!

Love this eyeliner. It really emphasizes on "Colorstay" because it stays on ALL DAY. Possibly more than 24 hours for sure! I use this eyeliner to tightline my eyes & it never comes off. It's so black and creamy. It glides on like butter which definitely helps for those with shaky hands. One of the best! Also love the fact that it's retractable! Highly recommend this eyeliner because it's one of my HGs. continued >>

I use and like Chanel and Urban Decay eyeliners. I bought this (black) on the recommendation of a friend. I liked that it was an automatic pencil as the other ones I use are not, and I have to sharpen them. The consistency is very hard and waxy. Application was difficult. I had to keep going over the lid several times to deposit color, and the pencil tugged and pulled at my eyelid. The shade black isn't very black or dark, it is more of a dark grey. I ended up tossing it after using it three times. The only redeeming quality that this eyeliner had was that it didn't smudge. I would not re-purchase.

I've been using this eyeliner for years! It's the only one that doesn't crease and actually does stay on. I usually only have to touch it up once during the day. Great product!

too much tugging on my lid/skin.

i prefer other liners that doesn't apply with much difficulty.

To put it simply, this is the only liner that stays on my waterline for at least the whole 7 hour school day. I may have to reapply once, if it fades, but that does not usually happen. I'll just say that I've had my fair share ofeyeliner horror stories with other pencils but I'll save that for another day. Love the twist up pencil as I'd rather not get chunks of wood in my eye like I would with sharpenable sticks. The sharpener on the bottom is so convenient altough I rarely use it. Safe for my contact eyes, I have had no issues with that. Like another person said, I like to blot my waterline with a q tip before applying. It works wonders. I will always repurchase.

Not a bad liner. Decent consistency, pretty good staying power. I've found that I prefer softer, creamier liners as they're easier to apply and are more easily manipulated if you need to fix mistakes--this one is on the harder, waxier side. I do love self-sharpening liners, but don't even bother with the sharpener hidden in the cap--the tip will just break off and get stuck inside, leaving it useless.

A good eyeliner lasts longer if set with a black eyeshadow.
