I bought the waterproof one in the colour "Very Black". It was about $6 on sale.
The first time I opened this mascara, I was immediately surprised by the size of the brush. It's so small! But I guess I'm used to very big mascara brushes, often using mascaras such as Volum'Express Falsies & The Collosal by Maybelline, LashBlast by CoverGirl, and Avon's SuperSHOCK.
At first I thought it would take a lot more work to coat all the lashes because of the small size of the brush. But I actually quite like the size - it makes it very easy to coat all your lashes, including the ones in the inner corner of the eyes, and it definitely makes lower lashes easier to coat as well.
This is a great everyday mascara, and I definitely think I'm going to keep one on hand all the time from now on.
