The mascara is just a normal one. It does lengthen but not crazy long. It is good for daily. I guess you can layer it but I feel that it clump my lashes. I really kind of regret getting extension 3 years ago. I feel that my lashes doesn't fully recover and every mascara will easily gives me spidery lashes. It is bad. But if you ask if I will get extension again, I will say yes. The brush is a normal bristle with one side longer than the other. It is nice to get through your lashes. The shorter side will helps to give a little volume. Overall it's a good daily mascara for me. But I do prefer others.
