Colossal has a big, regular soft brush. I wasn't expecting it to give me any massive results or fine definition but it turned out to be quite nice! It promised to give my lashes "up to 7 x more volume" and "no clumps". Well, it did a good job.
I think my lashes look thick and full, so it did give me the volume that I wanted. Also it did a pretty good job when it comes to definition, allthough it couldn't reach the level of a really good rubbery brush. But still pretty close.
The Colossal waterproof holds my curl all day, that is the reason why I use waterproof in the first place. It's quite easy to remove too. Plus it gives me pretty lashes with volume. All this at a cheap price...You must like that!
The only thing that I don't like is that because the brush is relatively big, it's sometimes messy to use. I'm used to smaller rubbery brushes now and going back to a bigger regular one has increased the consumption of Q-tips in my household in the mornings :) But I don't mind, as long as the results are this good.
Thanks for reading!
