State of the art

Magnetic false eyelashes have been on the market for several years as a consumer product. Despite their popularity among many fashionable consumers, they have obvious disadvantages, which include the following:

1. Existing magnetic artificial eyelashes mainly use 3-10 magnets, which are glued to the base of the eyelashes with a quick-drying chemical glue, evenly applied along the length of the base, most of the magnets are characterized by a large size of 3 mm (length) × 1 mm (width) × 0.3 mm (height), and convexity, each magnet is angular, which gives significant relief when gluing them to the base, and the edges and corners easily scratch the skin around the eyes, which brings inconvenience when wearing, and the magnets are easily peeled off, which reduces the duration of their use, thereby increasing the cost of use;
