I love this eyeliner. It lasts all day and night. My eyes water a lot and the waterproof takes care of that problem. The sharpener that fits in the end of the pencil is wonderful. Never have to look for one and it gives a nice point to the pencil.
I've been using this eyeliner for several years now and won't use any other product! It goes on smooth and is smudge free. No goopy eye boogies in the corner of your eyes with this eyeliner.
This is the best eyeliner. It is soft enough that it doesn't tug. Stays on all day but washes off with my facial cleanser. My favorite is the espresso (a dark chocolate brown) I just purchased the taupe and it is very nice neutral. Can make the line as heavy or thin as you want. I highly recommend.
