WOW, you had me worried there, you think you could have actually installed the ipad into the case instead of just laying it over the iapd. I thought the camera and holes didn't line up.
EDIT: NVM, I see now that the "ipad" in your pics is just the paper insert it comes with.
Do you have a spigen tough armour case that you can compare the rubber too? I have one for my 5s so I will be able to compare. the rubber is semi hard on the original I have.
I don't have my ipad here. It's the cardboard cutout that has a picture of a camera lens.
The rubber is a bid harder, but a so so simulation of the real Spigen rubber. It's bit more slick, cheaper feeling.
