This is a very cool little mascara. It has a very small brush that I find great for my lower lashes and those difficult to reach lashes on the top.
The formula is nice and black, but it can be a little bit clumpy, but that's no big deal when you are using it on your bottom lashes as you can just pick off the little clumps.
I find it takes longer to dry that most of my other mascaras, but this isn't an issue, unless you are a "I just put mascara on, so I'm going to sneeze" type of person like me.
I absolutely LOVE this mascara for my bottom lashes. I usually have the problem of mascara smudging whenever I try to apply it to my bottom lashes (it's usually so bad, I hardly ever coat them in anything!) But this mascara is absolutely incredible. The small brush coats my lashes well, making them look long & gorgeous, without smudging or clumping. I highly recommend using this amazing stuff for your bottom lashes.
