Stays on
Would give it 4.5, Expected the wire bristle brush to be a better separator,  but its not that great, I only bought it because of the bristle brush I usually use a different brand but wanted to try something new.  However the mascara is pretty good,  make sure to build it up, can get pretty good length and volume.  Staying power is something else.  Does not come off.  Make sure to get a good remover,  doesn't come off with soap and water.
