We love the felt tip because it makes creating clean lines and the perfect cat eye a simple and less messy process. Plus, its long-lasting formula doesn't budge, which is particularly important when you're working all day in the office.. How To Use It. Make sure you shake the liner before use. To create the perfect flick, follow the natural shape of your lower lash line, then as you reach the curve of your eye, place a dot. Next place a dot in the centre of your eye, then connect the two dots and start to fill in, moving toward the inner corner of your eye. Voila! You have your perfect cat eye.. Top Tip: Keep a cotton bud close to erase any mishaps.
