I hate doing eyeliner on myself. It has taken years of practice to get that perfect line and perfect wing. Most of the time I am in such a hurry, I forget to do the wing and just go. But with this great waterproof eyeliner pen and stamp combo from Jisener, I no longer have to worry about my wings being lopsided or way off. This pen has a great stamp on the back that gives the corners of your eyes the perfect kitten sized wing. The pen dries quick and is completely waterproof without the run effect if your face gets wet. The pen has a sturdy tip and glides on seamlessly. This makes it easy for people who have struggled with eyeliner, like me, achieve a great lined eye with ease. This has become my go-to eyeliner for my makeup routine. It's just so easy to use. My daughter also loves it. This is a great buy.
