With its comfortable use, the eyelash curling machine allows you to get curlier and longer eyelashes before make-up application. WHEN APPLYING, put your eyelashes between the eyelash curling machine and squeeze lightly. After holding it tightly for 5-10 seconds, slowly loosen the eyelash curling machine. If you are going to use mascara, you need to apply the Eyelash Curler before applying mascara. If you apply it after mascara, you may damage your eyelashes.
