Review (5/5): I don't use any other eyeliner, period.
I'm not sure how this product isn't working for others? It doesn't smudge, lasts OVER 24hrs, and dries super fast! I've used it for years. This one liner
pen, though yes should be gotten rid of after 12 months, has enough in it to wear it daily for over a year. I've had the same one for over a year and a half now (repurchasing today as its finally nearing the end) and I use it daily. I do NOT have steady hands, so this tip makes my eyeliner look pro without much effort on end! And I'm amazed that the tip has held up this long!
Really well made product, 10/10 highly recommend. I use baby oil to remove it, as it's definitely waterproof. And that price?? Totally worth it to give it a shot if you haven't already.
