This is what I got:

I will get my case on Monday, so I will see how they look together. This is the 3rd time fate has stepped in and corrected
a mistake I made in the world around my kindle...!
A book I bought on eBay a few weeks before I even thought about buying a Kindle, never got shipped! I was regreting buying it
cause it was cheaper on the Kindle and it weighs a ton. She refunded me!
A case/pouch I bought, also on eBay, then regretted when I found something else I liked better... was out of stock, refund!
Now this!
The Kindle Gods must like me or something!
p.s. I found them very easy to put on and it really gives it totally new look... =)!
This looks just like the skins we buy from various vendors, such as Decalgirl. The Amazon forum you linked to calls them vinyl, not silicone. (The title of the thread was Kindle silicone skin and neoprene cover).
Very nice combo, though.
