All-time favorite black liner

I work at a gym and run/do hot yoga/get generally sweaty every day, and this is my all-time favorite black eyeliner. It stays in place, is easy to apply, doesn\’t melt off after a few hours, and is a beautiful, dark black. Basically, it\’s the perfect black liner and I recommend it to everyone (and that\’s coming from a liner addict who has tried dozens of options).
