I just picked two of these up on Ebay for $8.99 shipped. The only way I can describe them is a silicone skin/hard case hybrid. It's basically a silicone case with a hard cover that holds the silicone case on a bit better plus gives a little bit o' hard cover type protection. Every silicone case i've had in the past liked to slip off pretty easily - this doesn't feel like it's going anywhere anytime soon! The ones I got were the lime green and carbon fiber variants, but they can be also had in pink, blue or black. I thought the lime green with black screamed Android! If nothing else, they are definitely unique! Ebay seller's name is "moderntechs" . Search with keywords on Ebay "Nexus Hard Silicone" and you'll pull them right up!
