These lashes are now part of my life. I can never go back to just mascara. I am ruined. And I love them. They last about a week. Ive surfed with them, showered, slept and sweated and they stay put. Just remember to try not get them wet for the first day of application, the glue needs a bit of time to become waterproof. My favourite is Yvette 10 and 12mm legnths to look natural enough for everyday but still glam. xxx
