Hey Michael,
None of my Essences even came with cases. Strange, considering what they cost. I purchased generic rectangular cases for them here. They work fine but since the Essence has such a narrow body, there's quite a gap between the body and the interior sides of the case.
I recommend that (if you're ordering a new Essence) you request a case with a form fitting interior - G&G make the best cases.
You can also easily stuff it in a gig bag.
