This is a great, basic, long lasting mascara. The brush is natural brissels, they are short and hard and the spirals are slightly widely spaced apart. The brush shape is small and almost hourglass shape, the tip is almost pointy, it's an odd shape. I don't find that this mascara is does much for my short, sparse lashes. It doesn't add much volume, or length, it does make my lashes super dark. The product doesn't build great and almost acts like a waterproof mascara, it's super hard to get off.
