Clinique's mistake-proof pen creates a clean line in one steady sweep. Tapered precision brush paints on pure, deep colour from thin to thick. 24-hour smudge- and budge-resistant wear. Ophthalmologist tested. Allergy tested. 100% fragrance free. To create a thin line: use the pointed tip of the brush. To create a thick line: use the flat side of the brush. To create a tight line: while looking into a mirror, tilt head 10 degrees back, making it easier to see the lash line. Starting at outer corner of eye, draw a line to the middle of the lashline. Repeat from inner corner of eye, connecting to the first line. To create a cat eye: start with the tight line as directed above. Create the perfect diagonal line for your eye shape by drawing a short thin line upward towards the outer corner of your eyebrow. Made in USA.
