I have to disagree with the other review on here. I didn't find this mascara to be clumpy at all. The rubbery/plastic brush is nice, much different than your typical mascara brush. Plus the fact that its a rubbery material means if you wanted to you could wash it from time to time for that fresh new mascara brush feel.
This mascara gave me nice natural coverage and great length. I honestly don't have any clumping at all. The bristles keep your lashes seperated as you apply which is what gives you that nice clean look. You don't get an overload of mascara on the brush, I think it gives you just the right amount. If you like the real heavy mascara look, then this isn't for you.
One thing to note. The product comes packaged with the brush next to the tube so you might be wondering if you have to keep them seperate. You do not, its just packaged that way to showcase the brush tip. Once you take the cap off of the mascara tube the brush fits in and screws on top like any normal mascara would.
This is my new favorite mascara.
