Not something that couldn't be found elsewhere. Plenty of elsewheres, and for less money (even for good versions, not just “matte black oxide that isn't water soluble.”) But a deep black matte is virtually a staple in an eyeshadow range, so let's see what Onyx has going for it:
<ol>
<li>It has no leave-behind, no sooty residue. Yet it will blend fairly decently.
<li>It will blend, but I didn't have the best of luck getting it to truly "smoke out" by itself. Other colors will blend with it, but it won't soften on its own very well.
<li>It foils well with water or with other mixing media.
</ol>
<p>So...not unique, but a good serviceable version of a matte black eyeshadow/liner.</p>
