Okay, let me start off this review by saying that I made a big mistake. I actually bought this in brownish black instead of black (from the US). Yep, I bought the wrong shade but luckily this shade was more on the black side than brown, it just wasn't jet black.
I got curious about this mascara since this is THE mascara that started it all, so I bought one.
The wand is just your ordinary mascara wand, nothing special about it.
Here's how my lashes looked like after 2 coats of Great Lash:
On the left is a picture without mascara, and on the right is with mascara. As you can see, although it did add some length, I wouldn't call it a crazy improvement, just right.
Unfortunately, like 80% of mascaras, this failed to pass my oily eyelids test. Even after I coated this with my Clarins Double Fix Mascara, one eye got smudged pretty badly when my eye got a little wet from the dryness I felt from my contact lens :(
This mascara is good for those who want a natural look and don't have extremely oily lids like me, but like most mascaras, this is not waterproof enough for me :(
