Wow, I may have to look into these then. I love the ELF eyebrow kit but they don't have the lasting power to survive my job (I'm a Taekwondo Instructor). The espresso looks pretty close to my brow color, I may have to pick one up next month and give it a try.I tested a few at Ulta- they were missing the brunette shade for some reason.
Good god, these things do not BUDGE. They are the most waterproof thing I've ever used. Took forever to remove, but that's awesome, I WILL BE BUYING just as soon as I can decide the right clolor.
Even thinking about using the dark brown for eyeliner or mascara ...
