EasyAcc Galaxy S7 Edge Clear TPU Case
If you're here for a quick and simple case that's cheap, this is it. Solid TPU cases are often priced extremely low, but offer plenty of protection.
EasyAcc has a nice TPU Galaxy S7 Edge case with raised and rounded edges to keep the phone safe at all times. The sides slightly curve to keep the sides of the screen accessible. This is a cheap case that will get the job done, and it does so while being one of the thinnest in our list.
