A fast application eyelash decoration using flexible magnets as a carrier, comprising: a first flexible magnetic strip (10) having multi-pole magnetization, a plurality of pairs of magnetic poles (11) being formed on the first flexible magnetic strip (10); a second flexible magnetic strip (20) having multi-pole magnetization, a plurality of pairs of magnetic poles (21) being formed on the second flexible magnetic strip (20); an upper eyelash decoration (100) comprises the first flexible magnetic strip (10) and a first false eyelash (30), a root portion of the first false eyelash (30) being coated with a magnetic conductive glue (50) having high magnetic connectivity, wherein the magnetic conductive glue (50) forms a magnetic loop with the first flexible magnetic strip (10); a lower eyelash decoration (200) comprises the second flexible magnetic strip (20) and a second false eyelash (40), a root portion of the second false eyelash being coated with the magnetic conductive glue (50) having high magnetic connectivity, wherein the magnetic conductive glue (50) forms a magnetic loop with the second flexible magnetic strip (20). When in use, the first false eyelash (30) is connected to a lower side of real eyelashes (60) by means of the attraction between the magnetic conductive glue (50) and the first flexible magnetic strip (10), while the second false eyelash (40) is connected to an upper side of the real eyelashes (60) by means of the attraction between the magnetic conductive glue (50) and the second flexible magnetic strip (20).
