This is my go-to everyday eyeliner. It is jet black and very dramatic (most might like it for evening but I can't live without it). I've been using it for several years. Must use it with the Bobbi Brown eyeliner brush or something similar. It's a little pot but it lasts me about 7-8 months. Would HIGHLY recommend. Makes eyes pop for sure.
The only eyeliner that I've found that doesn't run onto my undereyes by the end of the day. I have very dry skin and use a super moisturizer so my mascara and eyeliner would always melt onto my skin just under my lower lashes and create a shadow. This stays put, I tested it without mascara for a long work day and it does work. Goes on great with BB's eyeliner brush.
