I have had this specific mascara for a little less than a year and it is a good one. Sometime in early 2009 I did a make-up overhaul and bought a new batch of lip glosses, eye shadows, mascaras, blushes, eye liners, cover up, and random make-up items. In this batch of new make-up items I snagged this mascara.
The claim for this mascara is that it will make your eyes look brighter and more colorful due to the metallic tint. I have blue eyes so I bought the Black Sapphire tube for around $6.00, that is a price point that I can get
As you can see there is a difference with my eyelashes. They look longer and they look a little darker. I have a hard time telling if the metallic tint actually does anything or if it is just a gimmick. I do like the mascara consistency, it is nice and smooth and does not clump at all. The brush is not the "bristley" kind that has lots of separate fibers. It has a rubber brush with rows of tiny rubber digits.
All in all this is a good mascara that does not smudge when I rub my eyes, it does not clump, has a good consistency, and was a good price. But, I just don't see the "eye brightening" that they claim will happen.
