You can wear them with or without mascara.
You don't need to wear mascara to wear the Magnetic S'Attraction Eyeliner Lashes or keep them on. However, we suggest that you put a layer of mascara on your natural lashes prior to putting on your S'Attraction Lashes. Although it is not needed it does look nice because it blends the color of your natural lashes to the color of the S'Attraction Eye Lashes. BUT we do not recommend that you put mascara on the S'Attraction Lashes
