New automatic eyeliner from Infallible. Get intense strokes that last up to 36 hours New automatic eyeliner from Infallible. Get intense strokes that last up to 36 hours and resist everything: water, sweat, it's even scratch-proof. You can obtain either a precise line, thanks to its automatic tip, or a blurred effect, thanks to its sponge. It is also suitable for sensitive eyes. Benefits: Create sharp lines or faded lines with the End Blender and once dry it won't transfer. Sharpen the tip by pulling the sharpener, as it includes a pencil sharpener.
