Using these BEN NYE eye liner pencils is easy. Just hold the pencil like you would a regular writing pencil and gently glide it along your lash line. To get a smokey look, use a cotton swab or a smudging brush to blend the liner right after applying it. Then, to make the color last longer, apply Ben Nye's Eye Shadow on top. When you're done using the liner, put the cap back on tightly to prevent it from drying out. Keep it in a cool, dry place. Avoid getting it in your eyes directly and if it does, rinse your eyes thoroughly with water. These liners are designed for multiple uses, with about 50 - 175 applications per pencil, so make them last by using them sparingly when you don't need a thick line.
