Always curl lashes before applying mascara. 1\. Open eyes wide to insert and center lashes. 2\. With curler pad placed at base of lash line, hold handles firmly and gently squeeze. 3\. Hold for a few seconds, then open curler slowly to release lashes. 4\. Repeat up the length of lash from base to tip for an even more intense curl. Precautions: Clean after each use. With daily use, Tweezerman recommends replacing curler pad after three months and curler after one year.
