Love This. I have been using this eyelash curlor for about 2 years. I had used mechanical curlers since I started using makeup. Now I will never go back. In the past my eyelashes would pull out every now and then no matter how careful I was. Now they have grown back and I can get the most custom curl to my lashes. I use waterproof mascara and the curl literally lasts until I take off my mascara. Be sure to curl while the mascara is still soft.
