MICROFIBRE FORMULA - This 4D silk fiber mascara product uses ultrafine silk fibers to visibly lengthen lashes and create a dramatic curl.

Its oil-free formula preserves your makeup and ensures a perfect look, whether it is raining or exercising. Resistant to cold water and perspiration, volume mascara ensures a flawless hold even in hot weather. NO FALSE LASHES NEEDED - These volume mascara false lashes offer dramatic lengthening, perfectly coating each lash for naturally thick, curled lashes, without the need for false eyelashes. 4d silk fiber mascara creates a natural finish, defining each lash and increasing their density.
