White leather flip case, by BlackBerry.
Attachment 230458
One if the earliest posts on this thread wrote that the BlackBerry leather case was black. It's also available in white.
I saw it on bell.ca Web store and ordered it from there. Canada Post delivered it. Express. Shipping cost was included in the web price.

I enjoy this phone naked too. No back. Backless. It is easier to work with, in my experience, when backless. Here's a photo of my z30 backless.
I've placed my fingers lower than centered, to let you read the stuff printed on the back.
