The black mascara is a fantastic product. It's simple to use: simply wipe down the screen with it, then rinse and dry. The tube has a two-sided wand that can be used on both sides. When applying, I recommend using the first side, which is white primer. The second tube is black mascara again. Lightly touch all of the lashes with white primer once more. Use a gentle motion rather than a side to side sweep when moving the wand over your natural lashes. After clumping, it's difficult to separate any individuals lashes, which is true of any mascara.
