Tauri Thin-Fit TPU Case
Many of the cases outlined here are excellent choices, but they're also expensive. Lots of users prefer something simple, thin, and more importantly cheap. That is where TPU cases come in.
Tauri uses a soft flexible plastic material that does a great job at protecting every aspect of the Pixel. Each button or port is easily accessible, and easy to press. And the TPU material is raised around the edges to protect the screen even if it's laying face-down on a table.
These are cheap but do a great job. Choose from one of five different colors.
