Review: I hope they don’t discontinue this eyeliner. I’ve been using it for 8 years, and every time I try another eyeliner out of curiosity, I regret buying a different one. The brush holds just the right amount of liquid, so the lines are always sharp and vivid. I wear it every day, and it never smudges or creases. I recommend taking it off with an oil based makeup remover. one pen will also last you for a while.
Review: Very good and handy to apply but glue to my upper eye

## Questions & Answers

**Q: The ingredient black 2 (ci 77266) shows up as pretty toxic, but isn't this brand supposed to avoid toxic ingredients?**
A: All I know it is one of the best eyeliners around , I have used it for a while now no problem.. If concerned about being toxic I wouldn't use anything then..

**Q: What’s the easiest way to get it off?**
A: At the end of the day when I wash my face, it comes off with my face wash (Neutrogena) or you can also use coconut oil.  I very much love the eyeliner.  I've used many in years past and this one is the best for ease of use or I use a Q tip to correct any small errors.  Its also great at not burning my sensitive eyes.

**Q: Does this contain any form of pfas (forever chemicals)?**
A: This item does not contain any form of PFAS.

**Q: Could this be used to fill in eyebrows?**
A: Yes, it could if you wanted a very dramatic look. It's very pigmented and would not give a natural look for brows as it's not a matte liner. But for dramatic brows I can see it working. It's not super shiny but it's not flat matte either. It is a very long wearing formula and it's easy to make thin lines accurately and to taper/feather the ends of the lines perfectly. Hope this helps people curious.
