This mascara is kind of expensive, but it is budge proof, waterproof and oil proof, for the most part. This also holds up my curled lashes, as my lashes generally do not stay curled after I put on mascara. The formula for this is also intensely black, and the wand volumizes my lashes beautifully. I can put on 2 coats of this without clumping, and this lasts all day, and well into the night.
