I have had several baby bottles of this one. I love the huge, hourglass fluffy wand. It gives me the look of a ton of lashes while lengthening and volumizing.
Nars Audacious Mascara
This is the deepest black I've ever seen. Super lengthening and separating for a dramatic look. This gives the effect of each lash being volumized with its thick rubber bristles. It even has the ball of bristles on the end to help get every lash. Only caveat, it definitely isn't water resistant.
Eyeko Black Magic
This mascara has the most natural effect. The curved brush keeps a curve. Lashes are lengthened, separated and clump-free. In my experience, this one doesn't give much volume.
