The price is also reasonable for a drugstore product, and the volume is quite generous as well. I'm a double-lidded person, so when I used just the black, the eyeliner looked too bold and intense. But using both brown and black together gives great color payoff and a nice application feel. Highly recommend it!
It's a shame that the product dries up quickly if you leave the cap open while doing your makeup.
The brush is included, but I ended up buying a new one.
To avoid the hassle of opening and closing the cap while doing your makeup, the inverted design blocks air exposure, so the product doesn't dry up as quickly, which is really nice.
