I’m not sure if this mascara is supposed to be huge for the collection or not, but the size of the brush reminds me of Big Fatty Mascara from Urban Decay, which is a bit bigger than the mascaras I normally use, but it wasn’t as if it was too big to be able to apply it normally. The purple is noticeable I think, but not super, super bright. My lashes are normally a light brown, so that may have something to do with why it showed up, it would probably show up less on darker lashes.
If you wanted this to show up SUPER purple on your lashes, I’d recommend using a lash primer that’s white as a base and applying it over that. The white base would cause the purple to really stand out.
