Being a Benefit employee I may actually get the sack for admitting this but after months of preaching to customers that Benefit's 'bad gal lash' (£15.50) is one of the best mascaras I have only just tried it for the first time myself!
Lucky for me it is actually a very good mascara and I will not be hunted down by an angary mob.
Heres the pros:
Separates lashes well
Very dark black, so gives a strong colour
For evening I like my lashes really clumpy and its almost impossible to do that with this mascara, although most people will think that is a pro, I do sometimes have to put a thicker mascara like Rimmels 'volume flash' over the top!
