Bluecell Wave Design Black Color TPU Case Cover for Google Nexus 7 Tablet Android 4.1 Jelly Bean + 2 Pcs of Black Color Stylus Universal Touch Screen Pen
I've used these TPU cases on a couple phones before, and love them. I've actually got this case in 'red' as well, which is really pink. The black looks much better on it. Provides a no slip grip, and the styluses aren't too bad either.
