This mascara has a good sized standard mascara brush. It's a good size for picking up all of your lashes with one sweep. The formula for this is kind of right in the middle, where it isn't too wet or too dry. The formula also does keep a curl, I find that if you layer this product you can build good volume. This does not clump even if you put on 2-3 layers. The colour is quite dark, but not as dark as some Jet Black mascaras out there.
I find that this product does deliver on most of it's promises, but it is quite pricey and it's not the best mascara out there.
