As a Girl, its pretty hard to do the Eye-lining stuff when I'm in hurry.Designer Ehsan Sayyad's Easyliner features a scanner with infra red laser diode that scans the eye length first and then performs the eye lining perfectly according to the various types and styles shown in the catalog. It comprises a brush with a soft tip that controls the line width, making it possible to draw a narrow line as well as a wider one through adjusting pressure on the tip automatically. The movement of the tip is based on the distance traveled by the EasyLiner on the skin which ensures the tip to go inside even if you are still pushing the gadget on your skin during the application of the pattern.
