I have had the pot of Tarte Amazonian Clay for so long now. I have it in the shade grey, which is a really ashy blonde/brown kind of colour which is generally great for me. I get all my eyebrow products in the same shades. I find when using this product I really have to take my sweet time to perfect it, and its hard to fill in the sparse areas to blend perfectly, that could very well be because I need a different shade. It does last for awhile. I don't LOVE the brush it comes with, I would prefer something more defining, but its not the worst. It's definitely worth the money as a little bit goes a long way. For my preferred results, I mix it with a brow pencil.
