Tauri Clear TPU Case
Now for something a little on the cheaper side, consider Tauri. This is the brand I used on my Galaxy Note 5 and Galaxy S7 Edge simply because their cases are thin, lightweight, cheap, and clear. As in the beautiful curved glass edges and metal design shines through, but it still protects absolutely everything.
The Tauri TPU case is a soft flexible plastic that will keep your Note 7 safe. It wraps over the edges to protect the curved glass without getting in the way of the Edge panel software features either. The soft design is scratch-resistant and comes in either all clear, or some clear choices with colored bumpers for added flair.
It's cheap and gets the job done, if you're looking for something like that.
