The brush really separate ur lashes.
I really like the brush in this mascara and it is ok for staying on.  My only problem is that it comes out way too much on the brush. So u have to scrape it on the top before using it. It seems to want to clump if u dont take it off before bed. Ive always used vaseline to take off my mascara so it comes off for me. My eyes water alot so i use the waterproof kind.
