Customer Feedback:
Love these products. I’m so happy my eye doctor told me about Twenty / Twenty. I have sensitive eyes so whenever I wore eyeliner it never stayed on and always irritated my eye. This eye liner is the first eye liner I have used in years that stays put and doesnt irriate my eye at all.
