RIMMEL SCANDALEYES GEL EYELINER WITH BRUSH LINER WATERPROOF 5 Emerald is a long-lasting, waterproof eyeliner. Use the precision brush applicator to easily draw a neat, crisp line that will not smudge, budge, or run for up to 24 hours. The perfect companion for your makeup bag! The flat packed version is more economical due to reduced postage costs; sealed and boxed versions are also available at a higher cost.
