not perfect at all rather difficult to use and did not work for me [SEP] no matter how i tried i just could not find any benefit in using this eyelashes guide template i am older and my lashes seemed to have thinned out and this appeared to be something i would need to be able to get mascara on those lashes that otherwise would not get anything because they are too thinned out and short that i would do more damage to the surrounding skin and the cleanup would usually remove what little had actually made it to the lashesi used different mascaras different magnifying mirrors to be able to see better nothing helped me to get this guide to work perhaps for someone who already has thicker well defined eyelashes i do not know it just did not work for me
