I love a good eyeliner pen because it just makes applying eyeliner to your top eye lid so much more easier. I still love the essence 2in1 eyeliner pen but was disappointed that it didn’t last long at all and left me with panda eyes. I do however have a very oily skin so it might work well with someone who has less of an oily skin. If there was a waterproof version I would definitely give that a try, I was impressed at how easily it applied but not so impressed that it didn’t last long.
