This my go to eyeliner. I have been using this eyeliner for years. It does sometimes gets smudges before it has dries if one blinks. However it is easy to wipe off with water or makeup oil and once it dries completely it sets. This is waterproof and doesn’t smudge.

I liked this eyeliner pen. the color cartridge must be purchased separately. I like the design of the pen, I like that the cartridge is seperate. I did not like the brush. I found it hard to draw an even line. That may have been a "me" situation. So I use it to draw beneath my lash line instead and I use a different liner to draw on my lash line for a cleaner line.

I've been using shu uemura's liquid eyeliner pens for 10+ YEARS. each pen lasts me 2-3 years and I only need to replace the cartridge maybe once a year. when my most recent pen finally broke down (note: I bought it at the end of 2019) because the brush tip no longer reached a point - I made a trip into Sephora to find a quick replacement. I figured there'd be decent dupes by now. yeah no. NOT A SINGLE LIQUID EYELINER APPLICATOR CAME CLOSE. Also what's up with all the foam applicators? I tried literally all the brands, bought the best one I could find (Make Up Forever) - but it was still totally disappointing. If you, like me, need crisp, delicate, sharp lines, an easy to remove and clean up liner (water will suffice) - this pen, which actually still has bristles, is the only thing that will do the job. Yeah I think I will be using these pens until I die.

This is my first time purchase shu uemura eyeliner, very impressive, very good eyeliner, easy to draw the line smooth, stay whole day and good quality. I will buy again .

I did not realize this is NOT a liner with ink!! I hope I can return it. Just opened it today and realized my mistake. Lame!!
